The approaches for promoting PP adhesion based on the surface modification

Polypropylene (PP) is one of the most promising thermoplastic polymer materials. However, the application of PP is restricted to coating and adhesion fields due to its high crystallinity, low surface energy and weak interfacial layer. This review introduces the modification approaches that can improve the coating or adhesion performance of PP, including the development of chemical oxidation and several novel methods of chemical modification, such as the grafting polymerization with high-energy inducement, organoborane initiator, reversible – addition – fragmentation – chain transfer and atom transfer radical polymerization.     

Application of thermo-responsive poly(methyl vinyl ether) containing copolymers in combination with ultrasonic treatment for pigment surface modification in pigment dispersions

The process of surface modification of hydrophobic organic (copper phthalocyanine (CuPc)) as well as hydrophilic inorganic pigments (titanium dioxide) in aqueous dispersions by employing tailor-made thermo-responsive copolymers and the colloidal stability have been studied as a function of temperature. The pigment surface modification is achieved by conventional adsorption and by thermoprecipitation of amphiphilic methyl vinyl ether (MVE) containing block and graft copolymers, exhibiting a lower critical solution temperature (LCST), with poly(isobutyl vinyl ether) blocks and poly(ethylene oxide) side chains, respectively. The effect of mechanical treatment of the pigment dispersion by ultrasonic power alone or in combination with the LCST property was investigated. The course of the pigment surface coating process was followed by the electrokinetic sonic amplitude (ESA) method. The temperature-controlled sorption of PMVE-g-PEO graft copolymers on both inorganic and organic pigment surfaces was investigated. It was found that ultrasonic treatment together with LCST thermoprecipitation is a promising method for the surface modification of pigments with regard to dispersion stability.     

Preparation and properties of polymer-encapsulated phthalocyanine blue pigment via emulsion polymerization

Polymer-encapsulated phthalocyanine blue pigment dispersion was prepared with a polymerizable dispersant by emulsion polymerization method, and the effect of preparation conditions on the particle size of dispersion was investigated. Dynamic light scattering measurement demonstrated that allyloxy nonyl-phenoxypropanolpolyoxyethyleneetherammonium sulfonate (ANPS) was suitable for phthalocyanine blue pigment modification. The polymer-encapsulated phthalocyanine blue pigment dispersion with the small particles was obtained when the mass ratio of ANPS to phthalocyanine blue pigment, styrene (St) to phthalocyanine blue pigment, and ammonium persulfate (APS) to St was about 0.2, 0.2, and 0.01, respectively. Transmission electron microscopy (TEM), Fourier transforms infrared spectra (FTIR) and thermogravimetric analyses (TGA) provided supporting evidences for the encapsulation of phthalocyanine blue pigment with the formed copolymer. The polymer-encapsulated phthalocyanine blue pigment dispersion showed excellent stabilities to freeze–thaw treatment and centrifugal force.

Plasma surface modification of silica and its effect on properties of styrene–butadiene rubber compound

The effects of surface modification of silicas by plasma‐polymerization coating, together with modification using a silane coupling agent for a comparison on the dispersion and physical properties of styrene–butadiene rubber (SBR) are reported. The chemical compositions of the plasma‐polymerization coating were characterized using FTIR and Auger spectrometer and it was found that the plasma coating was composed of C?C and C? H bonds. The surface modification of silica by either plasma polymerization or silane greatly improved the dispersion of silica particles in SBR vulcanizates. The plasma‐polymerization modification of silica improved the tensile modulus of SBR vulcanizates without deterioration of important basic properties such as tensile strength and elongation at break. © 2002 Society of Chemical Industry

Synthesis and application of a novel epoxy grafted thermosetting acrylic resin

A novel manufacturing process for high performance metallic can coating was carried out based on an epoxy‐grafted acrylic resin. Firstly, the epoxy resin was reacted with acrylic amide forming a ring opened product epoxy‐amide resin, and then the product obtained copolymerized with all other monomers, such as acrylic acid (AA), butyl acrylate (BA), hydroxypropyl acrylate (HPA), 2‐ethylhexyl acrylate (2‐EHA), methyl methacrylate (MMA), styrene (St), using free radical solvent polymerization in the presence of BPO. The resins prepared present the transparent appearance, and the target resin coating based on these resins exhibits excellent boiling resistance and chemicals resistance and can be applied as the protective coating for metallic can. The effects on the coating properties, such as amount of acrylic acid, 2‐EHA wt % between 2‐EHA and BA, amount of amino resin, amount of catalyst, and so forth, were investigated. In addition, the influences of polymerization time on the conversion ratio of monomers were also studied. Results show that under the optimal conditions, the target resin coating provides excellent physical and mechanical properties. The various properties tests for this coating have been performed in accordance with the standards of ASTM. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
