Grafted and cross-linked epm |
摘要 |
The peroxide catalyzed reaction of maleic anhydride and a saturated ethylene-propylene rubber of low molecular weight and the hydrolysis thereof produces a reversibly crosslinked product of apparent higher molecular weight by measure of Mooney viscosity but apparent unchanged molecular weight by reduced solution viscosity (RSV). The graft product of a low molecular weight semi-solid substrate can be recovered conveniently as a non-cold flowing solid which has utility as a low molecular weight oil VI improver and as an impact modifier for polar thermoplastic resins.
