1.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.
文摘: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。收藏指正
2.New monodisperse fluorescent microspheres with the size about 500 nm and PDI 0.2 were prepared by dispersion polymerization of dansylallylamine with styrene in methanol/water reaction media using polyvinylpyrrolidone (PVP) as a steric stabilizer and 2,2’-azobisizobutyronitrile (AIBN) as an initiator in suitable condition for imploiting the method of copolymer fluorescent microspheres. The microspheres emit at 515 nm.
以偶氮二异丁腈(AIBN)为引发剂,聚乙烯吡咯烷酮(PVP)为分散剂,在甲醇/水混合溶剂中,采用分散共聚法通过优化反应条件,制备出了粒径在500 nm、PDI在0.2左右的单分散苯乙烯与丹磺酰氯烯丙基胺共聚荧光微球,其荧光发射峰位于515nm。收藏指正
