POLYMERIC PEROXIDES DERIVED FROM HYDROXY-HYDROPEROXIDES AND DIHYDROXY-DIALKYL PEROXIDES AND THEIR USES Abstract of the Disclosure A polymeric peroxide comprising a divalent recurring unit having the formula: -[-O-R1-OO-(-R2-O-)Y Image (-X-R3-X1- Image )z-]- I wherein the recurring unit of Formula I has a 10 hour half-life temperature of at least 80°C and optionally a divalent recurring unit having the formula: -[-Y-R5-Z- Image -(-X-R3-X1- Image )z-]- IV wherein R1, R2, R3, R5, X, X1, 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.
