Abstract
Siloxy-terminated hydrocarbon polymers containing at least one polymer chain per molecule of the formula: ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are independently selected from saturated and unsaturated aliphatic and aromatic radicals, A is a saturated hydrocarbon bridging group optionally containing at least one aromatic group and --(M)n -- represents a polymer of an olefinic monomer, n having a value such that the average molecular weight of the polymeric chain is from about 1000 to about 5,000,000, together with telechelic polymers and radial polymers containing this unit.
