【摘要】 研究了当用热塑性树脂作为不饱和聚酯树脂低收缩剂时 ,合成了以苯乙烯为主链 ,聚酯为枝链的梳状接枝共聚物 ,作低收缩剂的分散稳定剂 ,配合相应组成的不饱和聚酯树脂得到了具有低收缩特性的不饱和聚酯组成物。更多还原

【Abstract】 Unsaturated polyester with low shrinkage composied of anti shrinking agent,thermoplastics,dispersion stabilizer,a kind of graft copolymer made from styrene and saturated polyester,shaped like a comb for its molecular structure and UPR in certain structure and some factors effecting on low shrinkage were introduced in this paper.更多还原
