ABSTRACT:
There is disclosed a cyclized block copolymer having a molecular weight of from about 10,000 to about 300,000 comprised of at least two different blocks, at least one of which blocks is a cyclizable block derived from a conjugated diene monomer of the general structure ##STR1## wherein, R.sub.1 is selected from a hydrocarbyl group containing one to twelve carbon atoms, R.sub.2 is selected from hydrogen or a hydrocarbyl group containing one to twelve carbon atoms; and at least one of which blocks is a non-cyclizable block derived from at least one member selected from the following classes of compounds:
