摘要： Production of a solution of a chloroprene polymer, suitable for use as a component for an adhesive, by dissolving the polymer in a solvent, and heating the solution, adding a free-radical catalyst and contacting the solution with a molecular oxygen containing gas, until the viscosity of the solution is lowered by at least about 10%.
