摘要
EPDM-g-SAN/SAN树脂、EPDM-g-MAN/SAN树脂和EPM-g-MAN/SAN树脂三种共混物的老化性能研究表明,三种共混物的耐气候老化和耐热氧老化性能都优于ABS;EPDM-g-SAN/SAN树脂和EPDM-g-MAN/SAN树脂两种共混物的人工模拟气候老化机理和热氧老化机理主要都是共混物的大分子发生-CH_2-脱氢、脱氰基、脱苯环和羟基先生成后脱掉的反应。
The thermal oxidative aging and accelerated weather aging results showed that the aging property of the blends of EPDM-g-SAN/SAN, EPDM-g-MAN/SAN and EPM-g-MAN/SAN were better than ABS. The aging mechanism was mainly the decrease of -CH2-,-C=N and benzene ring, and firstly the increase and then the decrease of -OH of the blends during aging process.
