摘要: 对丁腈共聚物(含丙烯腈40wt%左右)的Tg是有争议的。Boyer等认为有双玻璃化转变,也有人认为高温区的转变是液-液松弛T11。本文通过研究填充的丁腈共聚物动态力学性质表明共聚物有双Tg,还讨论了填料石墨、二硫化钼和白炭黑的补强效果。

Abstract: The glass transition temperature and the tensile strength of poly (butadiene-co-acrylo-nitrile) filled with graphite powder, molybdenum disulfide powder and silica were measured. The results showed that the copolymer filled with graphite has the highest tensile strength and percentage of bound rubber as compared with the copolymers containing either of the other two fillers. Tg (U) of the copolymer was verified.
