Polymeric peroxides derived from hydroxy-hydroperoxides and dihydroxy-dialkyl peroxides and their uses.

摘要

A polymeric peroxide comprising a divalent recurring unit having the formula: <CHEM> wherein the recurring unit of Formula I has a 10 hour half-life temperature of at least 80 DEG C and optionally a divalent recurring unit having the formula: <CHEM> wherein R<1>, R<2>, R<3>, R<5>, X, X<1>, Y, Z, y and z are as defined in the Detailed Description of the Preferred Embodiments and the polymeric peroxide has a molecular weight of 1,000 to 200,000. The polymeric peroxides are derived from hydroxy-hydroperoxides or dihydroxy dialkyl peroxides. These polymeric peroxides can be used for preparing block copolymers and compatibilizing polymer blends and alloys.
