A polymeric peroxide comprising a divalent recurring unit having the formula:
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:
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.
