Abstract
Method for producing a compatabilized rubber composition comprising blending a hydroxy alkylamine or a hydroxy alkylthioether functionalized polymer of a C.sub.4 -C.sub.7 isoolein and para-alkylstyrene with a dissimilar polymer.
Claims5
A method for producing a compatibilized rubber composition comprising:
- blending (i) at least one polymer comprising an isoolefin having from 4-7 carbon atoms, and para-alkylstyrene monomers represented by the formulae:
- ##STR5## wherein each R and R' are independently hydrogen or a lower alkyl, Z is a halogen or S--R.sub.2 (OH).sub.n, R.sup.2 is a hydrocarbyl radical containing 1 to 6 carbon atoms, and n is an integer of from 1 to 10;
- with
- (ii) at least one dissimilar rubber containing halide or carboxyl functionality in the polymer backbone.
