Process for preparing rubber-modified styrenic polymer compositions containing hydroperoxide derivatives of rubbery polymers |
摘要 |
Hydroperoxidized rubber-containing polymers are prepared in a process wherein a rigid phase polymer is prepared by polymerization of one or more free radically polymerizable monomers in the presence of a hydroperoxidized rubbery intermediate in a well stirred back-mixed reactor operating under essentially homogeneous conditions at a solids content of from about 30 to about 75 percent by weight, and an initial rubber content in the feed of from about 5 to about 12 percent by weight.
