Nonisothermal Crystallization Behavior of Syndiotactic Polypropylene
摘要
Abstract
Nonisothermal crystallization behavior of a syndiotactic polypropylene sample and an isotatic polypropylene counterpart were studied by differential scanning calorimetry(DSC) at different scanning rates. It was found that the crystalline structure of sPP was different from that of iPP. The kinetic parameters of crystallization, obtained from the corrected Avrami equation and Ozawa equation for sPP and iPP samples crystallized nonisothermally at various cooling rates, suggested that there were different nucleation and growth mechanisms existing between sPP and iPP samples. Because of the lower tacticity of sPP molecular chains, it had a lower rate of crystallization and a much lower degree of crystallinity, compared with those of iPP.关键词
