Abstract
PURPOSE: To prepare a liquid chloroprene polymer having terminal carboxyl groups, by polymerizing chloroprene monomer with a monomer copolymerizable therewith, in an organic solvent in the presence of a mercaptocarboxylic acid.
CONSTITUTION: To prepare a liquid chloroprene polymer having one or more carboxyl groups in a molecule, a number average molecular weight of 500W20,000, a Brookfield viscosity of 3,000W3,000,000 cps at 25°C, and an intrinsic viscosity of 0.03W0.25 measured in toluene at 30°C, is prepared by (co)polymerizing (A) 50W100 wt% of chloroprene monomer and (B) 50W0 wt% of a copolymerizable monomer selected from unsaturated glycidyl ester of formula (R is H, methyl, ethyl), poly-functional (meth)acrylates, and unsaturated carboxylic acids, in the presence of (C) 20W150 parts by weight (based on 100 parts of the total monomers) of an organic solvent having a boiling point of ≤150°C and selected from aromatic hydrocarbons, aliphatic halogen-substituted hydrocarbons, etc. and (D) 0.5W20 parts by weight of a mercaptocarboxylic acid, at 0W100°C.
