PBS基三元共聚物的合成及性能研究
Study on Synthesis and Properties of PBS-based Terpolymers
摘要
Abstract
introducing ε-caprolactone(CL) and 1,4-cyclohcxanedimothylene(1,4-CHDM), or CL and lglycollc acid(DGA) in the main chain at poly(butylene succirsate)(P8S) to produce PBS-r.o PCL-co-CHDM and PBS-co-PCL-coDGA terpolymers. The structures of the terpolymcrs were Identified by 'H-NMR and FTIR. The properties of the terpolymers were investigated by thermal analysis, WAXD and tensile strength testing. The results indicate that with the addition of CL. 1,4-CHDM and DGA, the sp hem Site size and crystallsnity of ierpoiymers decrease, the crystal form changes slightly compared with that of pure PBS. Tanδ increases, while storage modulus decreases; in the presence of CL, the addition of 1,4-CHDM increases the Tg of PBS-co-PCL-co CHDM to -30℃ , while the addition of DGA decreases the Tg of PBS-co-PCL-co-OGA to -36℃ . But the decomposition temperatures of both terpolymers are above 300℃; the flexibility of the terpolymers is improved, and the elongation at break also increases obviously.关键词
