AN IMPACT MODIFIER AND A POLYMER COMPOSITION COMPRISING THE SAME |
摘要 |
An impact modifier composition comprising one or more core/shell polymers which comprise a crosslinked core having from 98 to 99.9 wt% units derived from one or more acrylate monomers and from 0.1 to 2 wt% units derived from a crosslinker containing a vinylically unsaturated moiety with an acrylate free radical reactivity ratio from 0.8 to 1.2 and one or more non- acrylate vinylically unsaturated moiety(ies) with an acrylate free radical reactivity ratio(s) greater than 1, wherein the crosslinked core has a swell ratio in THF between 7 and 15 and a Tg equal to less than 10°C; and a shell having from 20 to 100 wt% units derived from one or more (meth)acrylate monomers and having a Tg of greater than 20 °C is provided. Also provided is a polymer composition comprising the impact modifier composition and a base structural polymer. |
