Abstract
A method for preparing an amorphous polymer chain in an elastomer which permits use of previously unavailable monomers while permitting control of crystallizability of the amorphous polymer chain. The method of the present invention thus permits an increased range of industrial scale production by broadening the range of raw materials which can be used and by increasing the design options in constructing the chain.
