Abstract
Odorless functional (co)polymers are prepared by polymerizing, for example via aqueous emulsion, bulk or organic solution polymerization, at least one olefinically unsaturated monomer, e.g., styrene, butadiene, a (meth)acrylate or a vinyl nitrile, in the presence of a molecular weight/crosslinking-regulating amount of a conjugated diene chain-transfer agent having the formula (1): ##STR1##
