High Oil-absorptive Composites Prepared from Non-woven Fiber and Sponges with 4-tert- butylstyrene-EPDM-divinylbenzene Graft Polymer

4-tert-butylstyrene-EPDM-divinylbenzene graft terpolym-er (PBED) was prepared by graft cross-polymerization in toluene using BPO as an initiator. The gel-PBED and sol-PBED were isolated from extraction of tetrahydrofuran (THF), and then they were identified by IR spectr-oscopy. The maximum oil-absorptivity of gel-PBED produced from the optimum reaction conditions was 8420% but its swelling rate was very low. The highest oil-absorptivity of photocrosslinked sol-PBED film was 5 800%. Although its oil absorbency was not as high as gel-PBED' s, swelling rate was higher than that of gel-PBED and was suitable for commercial purpose. After swelling in oil, neither gel-PBED nor photocrosslinked sol-PBED film having high oil-absorptivity had sufficient mechanical strength to be taken out of oil wholly. As is known, composite technique is one of the useful methods for reinforcing them. Fibers, sponges and non-woven cloths were used as reinforcers or supporters in this work.

Effects of the Water in Mixed Solvent on the Epoxidation Reaction of Propylene with TS-1 Catalyst

The epoxidation reaction of propylene and hydrogen peroxide with zeolite catalyst containing titanium-silicalite (TS-1)has been studied, and the reaction in the mixed solvent of water/methanol has been discussed. It is shown that the selective of epoxidation propylene decreases while the selective of propylene glycol increases, when the water content increases in the mixed solvent of me thanol/water.

Study on Surface Optimization by Ion Beams

Preliminary tribo-mechanical properties of IBED filmsof GCr15 bearing steels have been studied in this paperalong with the comparison between IBED films and PVDfilms as well as non-implanted surface in wear resis-tance,micro-hardness,friction and surface morpholo-gy.Experiments gave a consistent picture and statedclearly that TIN films can really improve the tribo-me-chanical properties of materials and have practical usesin a certain sense.However,further theoretical and ex-perimental studies must be performed in respect thatthere are some defects on IBED films.
