    摘要： A latex of a chloroprene polymer formed from one or more monomers comprising 2-chloro-1,3-butadiene as the main monomer ingredient, characterized in that the solid matter in the polymer latex has a gel content less than 3 mass %, the solid matter in the polymer latex includes a tetrahydrofuran-soluble component having a weight-average molecular weight of from 550,000 to 1,100,000 and a molecular-weight distribution (Mw/Mn) of from 2.0 to 3.1, and the dried solid matter in the polymer latex has a crystallization rate (R) represented by hardness increase at −10° C. (R is the time required for initial hardness (time=0) to increase by 30 points at −10° C. as measured according to JIS-K6301) less than 60 minutes. The chloroprene polymer latex has an excellent balance among initial bond strength, contact adhesion, and water resistance. This latex is useful as an adhesive and can be used in applications where heat resistance of 60° C. or higher, initial bond strength, and contact adhesion are required.

    摘要： An aqueous latex, having high colloidal stability against coagulation upon addition thereto of ionic materials and having excellent adhesive characteristics for bonding metal foil to paper to form laminates, is prepared by polymerizing, in an emulsion substantially free of carboxylate soaps, (1) an aqueous suspension of chloroprene monomer optionally containing about 0.4 to 10 mole percent of alpha, beta-unsaturated carboxylic acid monomer, based on the total monomer content, (2) in the presence of (a) about 3-10 parts of polyvinyl alcohol and (b) about 0.3-2 parts of an organic, sulfur-containing chain-transfer agent of the group consisting of dialkyl xanthogen disulfides and alkyl mercaptans, both (a) and (b) being expressed in parts by weight based on 100 parts by weight of monomer (1). The polymer so produced contains 10-95% gel polymer, and the polyvinyl alcohol is present therein in a form such that it is not completely recoverable by extraction with water.
