20100010136 | CHLOROPRENE POLYMER LATEX AND PROCESS FOR PRODUCING THE SAME - 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. | 01-14-2010 |
