    摘要: In a reactor for continuous polymerization in which an olefinic monomer is polymerized by contacting the olefinic monomer under suitable reaction conditions with an initiator, the formation of residue in the reactor is reduced by introducing the olefinic monomer and initiator into opposite sides of a turbulent zone produced by an agitator in the reactor. This improves mixing of the olefinic monomer and the initiator and prevents the initiator from contacting high concentrations of the olefinic monomer which results in reduced residue formation in the reactor.

    摘要: A highly branched copolymer particularly suitable for forming pressure sensitive adhesives prepared in the presence of specified amounts of tert-butylchloride. Conjugated diene monomers are copolymerized with monovinylaromatic monomers in the presence of an organolithium initiator and a suitable amount of tertiary butylchloride. The holding power of adhesives prepared thereby is greatly increased.
