Abstract
An anionic polymerization initiator comprising the reaction product of a an organatin halide and lithium in a suitable solvent. Elastomeric polymers prepared with these initiators have tin containing functional groups on substantially every polymer chain and provide vulcanizable rubber compounds exhibiting reduced hysteresis. Articles such as tires, produced with low hysteresis elastomeric polymers have lower rolling resistance. Methods are also provided for preparing the initiators and the elastomers having reduced hysteresis properties.
