Synthesis and characterization of tall oil fatty acids-based alkyd resins and alkyd–acrylate copolymers

The polymerization and properties of environmentally friendly waterborne binders for wood coatings were studied. Conjugated and non-conjugated tall oil fatty acids-based alkyd resins were synthesized and further copolymerized via miniemulsion polymerization with acrylates (butyl acrylate and methyl methacrylate). The ratio between alkyd resin and acrylate monomers was varied and the effect on copolymerization and the copolymer binder properties, such as particle size, molecular weight, grafting of acrylate to alkyd resin and reaction of double bonds, were studied. It was observed that the use of MMA influenced on the degree of grafting of acrylate and monomer conversion because the steric hindrances prevent MMA to react with alkyd double bonds as eagerly as BA. The increasing amount of alkyd resin was noticed to decrease the polymerization rate. The research showed that it was possible to prepare stable hybrids, alkyd–acrylate copolymers, with varied chemical composition.

Effect of different polymers on the efficiency of water‐borne methyl amine adduct as corrosion inhibitor for surface coatings

Styrene/acrylic emulsion copolymer and water‐based short oil urethane alkyd resin were used as binders to prepare water‐based, environmentally friendly paints by using 0.5% emulsified methylamine adduct as corrosion inhibitor. The choice of the two above‐mentioned binders was based on the fact that styrene/acrylic emulsion copolymer is a nonconvertible binder, whereas short oil urethane alkyd resin is a convertible binder. The physical, chemical, mechanical, and corrosion properties of the paint films were evaluated and compared with a commercially known anticorrosive water‐based paint. It was found that the prepared paints have unique desirable properties such as the following: they do not contain anticorrosive pigments (which contain heavy metals in their main chemical structure); they are solvent‐free; and they can be produced to match any color. Corrosion tests on the films of the formulated paints revealed that the short oil urethane alkyd resin is superior to the styrene/acrylic copolymer. Moreover, the corrosion inhibition properties of the paint films prepared from both binders are comparable with the commercially available paints containing anticorrosive pigments. © 2002 Wiley Periodicals, Inc.

Structure of tall oil fatty acid-based alkyd resins and alkyd–acrylic copolymers studied by NMR spectroscopy

One- and two-dimensional NMR spectroscopy was used to evaluate the structure of tall oil fatty acid (TOFA)-based alkyd resins and waterborne alkyd–acrylic copolymers. An increase in the functionality of the polyol that is used in the alkyd resin synthesis was found to increase the reactivity of the polyol towards the diacid compared with the TOFA, which causes the formation of more branched and higher molar mass alkyd resin structures. During the copolymerization, polyacrylate chains were grafted to the double bonds and allylic sites of the fatty acid chains in the alkyd resin. Butyl acrylate preferentially grafted to the double bonds, while methyl methacrylate tended to graft to the allylic position. High proportions of the double bonds remaining after copolymerization were crucial to the film formation of copolymers, because the chemical drying of copolymer films occurred by an autoxidation process.

Study of reactive diluent for air-dried alkyd paint

The conventional air-dried alkyd resin is generally used with 30% to 40% of some organic solvent which dissipates into atmosphere after painting and becomes a factor of air pollution. A reactive diluent was investigated to reduce the content of the organic solvent and to manufacture a high-solid or superhigh-solid paint. 1,1-Bis(1′-methyl-2′-vinyl-4′,6′-heptadienoxy)ethane was found to be suitable as the reactive diluent among the investigated compounds. A small addition of this compound to alkyd paint reduced the content of solvent to less than 15% with a conventional alkyd resin of high molecular weight (high-solid type); and, further, a superhigh solid paint (5% solvent) could be manufactured when this compound was added to a superlong oil-length alkyd resin of low molecular weight.     

The influence of adsorbed layers on the rheological behavior of titanium dioxide dispersions

The aim of this study is to relate the influence of stearic acid on the rheological behaviour of titanium dioxide dispersions in alkyd resin solutions to the composition of the adsorbed layer on the dispersed particles.The adsorption of alkyd resin was studied using gel permeation chromatography. From the differences occurring in the molecular size distributions of the initial resin and the residual resin after adsorption, it followed that the adsorbed molecules extended throughout the whole molecular size distribution with a maximum at an equivalent chain length of 2800 Å.Stearic acid adsorption — determined using a radioactive tracer technique — was reduced by the presence of alkyd resin in the system.Titanium dioxide dispersions in alkyd resin solutions exhibited Newtonian rheological behaviour, showing that the adsorbed resin molecules protected the dispersed particles very well against flocculation. By counteracting the alkyd resin adsorption, the presence of stearic acid in the systems induced flocculation, leading to Bingham rheological behaviour. A direct relationship was shown to exist between the obtained Bingham yield values and the stearic acid adsorption.     

Synthesis of novel acrylic modified water reducible alkyd resin: Investigation of acrylic copolymer ratio effect on film properties and thermal behaviors

New four‐component water reducible acrylic modified alkyd resins that are based on 1,3‐propanediol and contain different ratios of acrylic copolymer (AC) were synthesized by using a novel four‐stage fatty acid method. The final content of solids in the water reducible acrylic modified alkyd resins was 60% by weight. After the modified alkyd resin films were cured at 150°C for 1 h, it was observed that the use of AC as the modifier component had improved their physical and chemical surface coating properties and thermal behaviors. Experimental results show that the optimum AC ratio is 40% of the equivalent amount of AC to alkyd resin. Low‐volatile organic compounds (VOC) content water reducible acrylic modified alkyd resins yielded soft and flexible films with high chemical/thermal resistance, suitable for manufacturing of surface coating binders.
