摘要 介绍了从熔体结晶生成的具有β晶型的等规聚丙烯(β-iPP)的生成条件,着重讨论了α晶和β晶独特的生长转变行为,包括在高临界温度和低临界温度下的生长转变。 Recent progress in studies on conditions of formation of hexagonal(β)-type crystal from the molten isotactic polypropylene(iPP) were reviewed with 20 references. The characteristic growth-transition of monocline(α)-and β-type crystals for iPP under the upper-and low-critical temperatures were also discussed.
