Synthesis and properties of novel high oil‐absorbing resin based on poly(ethylene‐propylene‐diene/ α‐methylstyrene/itaconic acid)

A novel high oil‐absorbing resin, P(EPDM/α‐MSt/ITA), was synthesized by suspension copolymerization with ethylene‐propylene‐diene (EPDM), α‐methylstyrene (α‐MSt), and itaconic acid (ITA) as monomers, benzoyl peroxide as initiator, and divinylbenzene as crosslink agent in this study. By using methods such as infrared spectroscopy, thermogravimetric analysis, and scanning electron microscopy, we studied the oil‐absorbing resin structure, oil‐absorption rate, oil‐absorption saturation time, and submicroscopic structure of oil‐absorption resin after oil absorption. The experiment results show that the highest oil absorptivity of the resin was about 21.9 g/g in diesel oil, obviously increasing the oil absorptive properties by the addition of itaconic acid as reaction monomer. We can draw a conclusion from scanning electron microscopy observation of sample after oil absorption that the oil‐absorption resin was filled with diesel oil, and a kind of morphology structure similar with embossment can be produced during the oil‐absorbing process. The oil‐absorbing resin was used repeatedly through the extraction by ethanol. Experiment result proved to have little effect on oil‐absorption properties. Otherwise, the oil‐absorption rate constant K of novel high oil‐absorbing resin was evaluated for diesel oil, and the oil‐absorbing process obeyed the first‐order kinetics equation. POLYM. ENG.

Agro‐wastes: Mechanical and physical properties of resin impregnated oil palm trunk core lumber

Agro‐wastes, oil palm trunk core or sap was utilized for the production of new palm‐wood material using phenol formaldehyde resin as a matrix. The kiln‐dried (moisture content 10%) oil palm trunk was impregnated with phenol formaldehyde resin using a high power vacuum pump. The oil palm trunk core lumber (OPTCL) was loaded with different percentages of phenol formaldehyde (PF) resin. The mechanical properties (tensile, flexural, and impact) and physical properties (water absorption and density) were studied and compared with rubberwood. Testing of mechanical and physical properties was done according to the ASTM standard. The morphology of the resin loaded OPTCL was analyzed by using Scanning Electron Microscopy (SEM). In general, the result showed that impregnated OPTCL exhibited good mechanical and physical properties when compared with untreated oil palm trunk core (OPTCL with 0% resin content) and rubberwood. Tensile and flexural strength of OPTCL increased with the increase in the resin content up to 15% and showed a decreasing trend with the increase in the loading percentage beyond 15%.The impact strength also increased with the increase in the resin content from 5% to 15%. However, impregnated OPTCL with 15% resin loading showed lower water absorption uptake as compared with the other composite materials and rubberwood. SEM micrograph confirmed that the resin was impregnated efficiently within the pores of OPTCL fibers. POLYM. COMPOS., 2010. © 2009 Society of Plastics Engineers

Studies on physico-mechanical properties of some new light weight engineering materials

Industrial, agricultural, and naturally occurring waste materials in conjunction with liquid epoxy resin, silica and asbestos were employed to make light weight engineering composite materials. To bring down the cost of the expensive resin, additives such as linseed oil and urea formaldehyde were added to replace the bulk of epoxy resin. Various physico-mechanical properties of these composites were studied. In comparison with ordinary cement concrete, properties such as water absorption and fire resistance improved substantially for the majority of mixes, whereas other physico-mechanical properties did not improve greatly in many cases. Such composites, which are similar to (and in some cases better than) ordinary cement concrete can be of use in building technology because of substantially lower prices.
