摘要
本文综述了淀粉接技丙烯腈的皂化,金属离子氧化反应引发接技共聚的机理,皂化后淀粉接技丙烯腈的吸水性能与淀粉分子聚合度的关系,吸水性能与接技共聚物中聚丙烯腈聚合度的关系,高吸水性淀粉中所含水的特性以及淀粉、聚丙烯、及其共聚物的热行为。
Saponification of graft copolymers (SPAN) of starch and polyacry- lonitrile(PAN), Mechanism of graft copolymerization onto polysaccha- rides initiated by metal ion oxidation reactions. The relations between water absorbencies of the saponified SPAN (HSPAN) and degree of polymerization (DP) of starch moleculer, the relatllns between water absorbencies of the HSPAN and DP of PAN in SPAN, characterization of sorbed water in HSPAN and thermal behaviour of starches and their graft copolymers with PAN are related in this review.
