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, one or more coupling agents and one or more powders. The sizing composition of the invention provides a glass fiber which has improved processability and notched izod without any loss in dispersability characteristics of the glass pellets.
