Abstract
Crosslinked rubber particles comprising an isobutylene polymer component, an organosiloxane polymer component and optionally a vinyl polymer component, or graft copolymer particles comprising the crosslinked rubber particles and a vinyl polymer grafted onto the crosslinked rubber particles, which are useful particularly for improving the low temperature impact resistance of thermoplastic resins without impairing weatherability and heat stability thereof.
