Title:
EP(D)MポリマーおよびEP(D)Mのポリアルファ-オレフィン混合物の粘弾性特性の改良方法
Document Type and Number:
Japanese Patent JP5175026
Kind Code:
B2
Abstract:
A process is described to modify the rheology of EP(D)M copolymers optionally mixed with polyalpha-olefins, which comprises treating in high shear conditions a polymeric mixture comprising one or more EP(D)M polymers, optionally mixed with polyalpha-olefins, in presence of one or more vinyl multifunctional monomers and of one or more hydroperoxides, with the amount of vinyl multifunctional monomer comprised between 0.02 and 2.0 by weight, preferably between 0.05 and 1% by weight, with the molar ratio between the vinyl monomer and hydroperoxide being comprised between 0.005/1 and 2/1, preferably between 0.01/1 and 1/1, said process being performed at a temperature between 75 °C and 260 °C, preferably between 140 °C and 210 °C.
