相转移催化在高分子化学中应用

相转移催化是一类合成技术,将固相或水相的有机或无机盐转移到有机液体中与有机可液物反应。 相转移方法应用于聚合物合成和改性。包括四部分:1.相转移催化自由基反应,丙烯酸类单体的聚合。2.冠醚用于双烯阴离子聚合和共聚合。3.相转移催化用于缩聚—聚醚的合成。4.相转化催化用于聚合物化学改性。

PHASE TRANSFER CATATYSIS IN POLYMER CHEMISTRY

Phase transfer catalysis is synthetic technique involving transport of an organic or inorganic salt from a solid or agueous phase into an organic liquid where reaction with an organic soluble substrate takes place.The use of phase traneler processes has been employed in polymer synthesis and modification. The paper consists of four sections. 1.phase transfer free radical reaction,polymerizations of Acrylic monomers. 2. the use of cr-own ether as a modifier in the anionic polymerization and copolymerization of diene, 3. Synthesie of polyethers by phase transfer catalyzed polycond-ensation. 4. chemical modification of polymers via phase transfes eatalysis.
