外给电子体对聚丙烯结晶性能的影响
The effect of external donors on crystallization properties of polypropylene
摘要
Abstract
Three kinds of polypropylenes(PPs) with different isotacticity and relative molecular mass were prepared by using three kinds of alkylsiloxane external donors.The effects of extemal donors on crystallization properties of PPs were introduced.The isothermal crystallization of the three kinds of PPs was tested by DSC and POM.The results showed that the isotacticity and relative molecular mass of PPs increased with the volume of alkylsiloxane as external donors.As increasing the crystallization temperature,the crystallization rate of PPs decreased.关键词
