Carbamate silicon compounds as latent coupling agents and process for preparation and use

摘要

Novel tert-alkyl carbamate silicon compounds are provided which are useful as coupling agents. The compounds have the formulas: <IMAGE> or <IMAGE> wherein the R groups can represent various hydrocarbon and other groups, n has a value of 1 to 10, b has a value of from 2 to 5 and a has a value of 1, 2 or 3. Processes are also provided for the preparation of the carbamate compounds and their use as coupling agents.
