ABSTRACT:
Haze-free, clear, impact-resistant resinous copolymers are produced by coupling polymer-lithium with a mixture of coupling agents wherein one is a lactone such as butyrolactone and the other is a halo-silane such as phenyltrichlorosilane. The combination of coupling agents reduces haze, yet maintains clarity and impact resistance of the resulting coupled polymer.
