PVP聚苯乙烯吡咯烷酮
关于它的溶沸点的介绍有熟悉的能说一下吗
以及它的一下性质越详细越好
我在网上没有查到详细的
不好意思
谢谢

聚乙烯砒咯烷酮是由乙烯基砒咯烷酮聚合而得。简称PVP,分子量5000～700000。 PVP是无臭、无味的白色粉末或透明溶液。具有优良的溶解性。低毒性、成膜性、络合性、表面活性和化学稳定性。可溶于水、含氯溶剂、乙醇、胺、硝基烷烃和低分子脂肪酸。与多数无机盐和多种树脂相溶，不溶于丙酮、乙醚等。
PVP的固体和溶液都很稳定，具有成膜性和吸湿性，其薄膜无色透明，硬而光亮。加入某些天然或合成高分子聚合物，有机化合物可有效地调节PVP的吸湿性和柔软性。PVP有很强的粘接能力，极易被吸附在胶体粒子表面起到保护胶体的作用，PVP有优良的生理惰性和生物相容性，对皮肤。眼睛无刺激或过敏，实际无毒，LD50＞13000mg／kg。
PVP主要用于制造喷发胶、发乳、摩丝，在头发上形成的薄膜富有弹性和光泽，梳理性能优良，不沾灰尘．还可用作增稠剂、分散剂、稳定剂等。贮存于阴凉、干燥的库房内．隔热、防潮、避光。
