ABSTRACT:
Epoxidized linear block, random, star-branched block or star-branched random polymers are disclosed which prior to epoxidation contain at least one conjugated diene having at least five carbon atoms of the formula (1) ##STR1## wherein R.sup.1 -R.sup.6 are each hydrogen or a hydrocarbyl group, provided that at least one of R.sup.1 -R.sup.6 is a hydrocarbyl group and the structure of the residual double bond in the polymerized diene of formula (1) has the formula (2) ##STR2## wherein R.sup.I, R.sup.II, R.sup.III and R.sup.IV are each hydrogen or a hydrocarbyl group, provided that either both R.sup.I and R.sup.II are hydrocarbyl groups or both R.sup.III and R.sup.IV are hydrocarbyl groups; and the remainder of the conjugated diene different from the diene of formula (1), has at least four carbon atoms of the formula (3) ##STR3## wherein R.sup.7 -R.sup.12 are each hydrogen or a hydrocarbyl group, provided that the structure of the residual double bond in the polymerized diene of formula (3) has the formula (4) ##STR4## wherein R.sup.a, R.sup.b, R.sup.c and R.sup.d are each hydrogen or a hydrocarbyl group, provided that one of R.sup.a or R.sup.b is hydrogen, one of R.sup.c and R.sup.d is hydrogen.
