ClIIR/PS接枝共聚物的相容性

THE COMPATIBILITY OF C1 IIR/PS GRAFTCOPOLYMER

本文用动态粘弹谱仪、透射电子显微镜和反相气相色谱法研究了ClIIR/PS双组份接枝共聚物的相容性。讨论了共聚物相容性与微区尺寸、玻璃化转变的关系,以及共聚物的相分离温度。

The compatibility of chlorinated isobutylene-isoprene rubber/polystyrene graftcopolymer(ClIIR/PS) was studied by dynamic viscoelastic spectrum measurement, transmissionelectronic microscopy and inverse gas chromatography. The domain size and glass transla-tion temperature of the copolymer with various ratio of two components have been examined.Kaplan's conclusion was found to be an essential but not an abundant condition for Cl lIR/PS graftcopolymer. Copolymer with a single T_g was made up of 150A domain.
