Abstract
A nonaqueous sizing for glass fibers useful for reinforcement of polymers. The sizing composition comprises one or more film formers miscible with the polymer to be reinforced and one or more coupling agents. The sizing composition of the invention provides a glass fiber which may be wirecoated with the polymer to be reinforced, eliminating the need for extrusion or pultrusion processing to make glass/polymer composite fibers, compound or pellets.
