TH31922A - Flexible, rubber-like, extruded compound with variable rate control. - Google Patents

Abstract

Extruded rubber-like elastic mixtures that include ABA 'rubber-like elastic block polymers', where each sign of A and A' is a polymer end block. And where B is the dissatisfaction conjugated diene monomer. Low levels of residual ethylene, polyolefins and transition metal compounds in fruitful quantities classified as uniformly distributed in polyphenol-treated mixtures. And Bocopolymer for To make a mixture Flexible, rubber-like, extruded rubber-like It is reconstituted to a sheet of elastic material and then decomposes after exposure to the oxidized environment by continuous heat Less than about 30 days, the transition metal compound may be Lime or complex of cobalt and / or manganese And will be added In the amount to give a mild transition metal of approximately 0.01% by weight in the extruding compound,
