Abstract
Glass fibers are coated with a mixture of an organo silane coupling agent, an oxidized polyolefin, and a carboxylated high molecular weight elastomer having a solubility parameter similar to that of polyolefin. In the preferred arrangement the coupling agent, polyolefin, and high molecular weight elastomer are in the form of an aqueous emulsion which is applied to the fibers as a coating at forming, and then dried. The silane coupling agent may be applied either as an initial coating or in mixture with the emulsions, and the coated fibers when dried are particularly adapted for the production of composites having a polyolefin matrix and a reinforcement of the coated glass fibers.
