规整聚苯乙烯接枝聚乙酸乙烯酯聚合物的醇解与分析

Alcohol Hydrolysis and PGC Analysis of Graft Copolymer of Polyvinyl Acetate with Polystyrene Branch

规整的聚苯乙烯大单体接枝于聚乙酸乙烯酯主链上形成的接枝聚合物,通过醇解,获得了两性聚合物,定量醇解分析和PGC分析表明:在两性聚合物中疏水成份为6.5％左右。

Graft copolymer of PVAc-g-PSt with well-defined structure and compositon is hydrolyzed by KOH-absotute alcohol in butanone, Amphipathic copolymer of PVA-g-pSt is obtained, and is possessed of a hydrophobic content of about 6.5% by means of alcohol hydrolysis quantitatively and PGC analysis
