Abstract
An improved process for the preparation of isocyanate group containing telomers of reduced viscosity by conducting the telomerization of an ethylenically unsaturated monomer with an organic isocyanate in the presence of an organic compound containing at least one sulfhydryl group.
Claims3
In the process for the production of an isocyanate group containing telomer by telomerization of an ethylenically unsaturated monomer as taxogen and an organic isocyanate as telogen with heating and optionally in the presence of high energy radiation and/or chemical radical-forming agents, the improvement which comprises conducting the telomerization in the presence of from about 0.1 to about 10% by weight based upon the ethylenically unsaturated monomer, of an organic compound containing at least one sulfhydryl group.
