Abstract
This disclosure relates to a block interpolymer comprising at least one diene block and at least one butyl block, wherein the at least one butyl block comprises residue from a functionalizing agent on at least one end adjacent to the diene block(s). The disclosure also relates to methods of making such block interpolymers. Also disclosed is a rubber composition comprising: (a) a block interpolymer comprising at least one diene block and at least one butyl block, and (b) a filler, wherein said at least one butyl block comprises residue from a functionalizing agent on at least one end adjacent to said diene block(s).
Claims20
A method of producing a block polymer comprising mer units derived from at least two reactants, the method comprising reacting a functionalized diene polymer with a functionalized butyl polymer, wherein the functionalized diene polymer and butyl polymer each include a functional group that is not a living end of the polymer;
- wherein the functional group of functionalized diene polymer reacts with the functional group on the functionalized butyl polymer.
