《Polym Degrad Stab》1992,38(2),119-124刊载Dow化学公司系列研究论文的第二报,研究中用苯乙烯与两种已商品化的具有酮官能团的单体共聚,例如与甲基乙烯基酮(MVK)和苯甲叉丙酮(BA)共聚制成SMVK和SBA。BA与苯乙烯共聚能力很差,这种情况下又由于它的挥发性小,致使在最后聚合物中有高的BA单体残留量。其共聚物SBA的C~(13)同位素核磁共振特性表明,聚苯乙烯游离基加到双键的两个碳 “Polym Degrad Stab” 1992, 38 (2), 119-124 The second bulletin of a series of Dow Chemical Company research papers is published in which styrene is copolymerized with two commercially available monomers having a ketone functional group such as SMVK and SBA were copolymerized with methyl vinyl ketone (MVK) and benzylidene acetone (BA). The ability of BA to copolymerize with styrene is very poor, and in this case again due to its low volatility, there is a high residual BA monomer in the final polymer. The C ~ (13) isotope NMR of its copolymer SBA showed that the addition of polystyrene to the two carbons of the double bond
