新型有机高分子型PVC热稳定剂的合成
Synthesis of a Novel Polymeric Organic Thermal Stabilizer for PVC
【摘要】 以经部分硝化和还原的低分子量聚苯乙烯为母链,利用其胺基和丙烯酰基异硫氰酸酯加成,合成了一种新型有机高分子型PVC热稳定剂——丙烯酰基硫脲接枝聚苯乙烯,其结构经IR和元素分析表征。
【Abstract】 A novel polymeric organic thermal stabilizer for PVC was designed and synthesized by acryloylthiourea grafting on polystyrene which was nitrified by HNO3 and then reducted by Sn powder to amine. The structure was characterized by FT-IR and elemental analysis.
