The thermal decomposition of 86 % vinyl chloride 14 % vinyl acetate copolymer wasstudied by the conductometry technique in the presence of nitrogen. The kinetics of stability andthermal degradation of vinyl chloride- co- vinyl acetate (PVC- co- PVAc) copolymer withcopper, copper oxide and tricalcium dicitrate (st) were investigated at various temperatures (150-180 oC ) in solution. The rate coe...

Hydrophobie Vinyl Compound, Enhancement Effect, Enzymatic Hydrolysis, Waste Paper Enzymatic hydrolysis o f waste papers in the presence of various vinyl compounds was carried out, and the addition o f the compounds such as methyl methacrylate, styrene, and vinyl acetate increased glucose yield resulting from the acceleration of the rate of the enzymatic hydrolysis. The optimum conditions existe...

Novel enzyme-mediated synthetic routes were developed to provide a new family of sophorolipid derivatives and glycolopid-based amphiphilic monomers. These compounds are of great interest for their potential use in immunoregulation, as well as for other biological properties. In the present work, an efficient lipase-catalyzed conversion of sophorolipid ethyl ester to (a) the 6'-monoacylated deri...

The combination of Ethylene-vinyl acetate copolymer (EVA) with nanoclay has wide commercial applications (such as packaging films and cables), which depend on the vinyl acetate contained in the main chain. As the vinyl acetate content increases, the copolymer presents less crystallinity and different mechanical behavior. EVA with 40 wt% vinyl acetate content (EVA40)/ organoclay nanocomposites w...

The reaction of alkaline 2,4-dihydroxyquinoline 1 and 1-tetralone 2 in 2% sodium hydrox­ ide solution with vinyl acetate afforded a brown solid 3, which on treatment with phospho­ rous oxychloride yielded 2,4-dichloro-3-[l’-(l-chloro-naphth-2-yl)ethyl]quinoline (4). The same reaction of 1 and chromanone 7 with vinyl acetate afforded 2,4-dichloro-3-[l’-(4-chloro2-methyl-chromen-3-yl)ethyl]quinol...
