A conjugated diene/monovinyl substituted aromatic hydrocarbon copolymer is stabilized by the addition of a complex acrylate, in combination with at least one of an alkyl thiopropionate, an organic phosphite and a non-acrylate substituted hindered phenolic compound.
Sequential charging of initiator and monomers in a multistage solution polymerization process involving conjugated diene and monovinylaromatic monomers wherein the final charge is a mixture of these monomers results in the production of resinous polymodal linear block copolymers each wit
The effluent from a lithium initiated polmerization, wherein a coupling agent is utilized to join two or more polymer molecules together, with the resulting generation of LiO--, LiS--, or ##EQU1## groups is treated with carbon dioxide and an excess of water and thereafter stabili
