A strand of glass fibres is impregnated with a sizing comprising (1) a coupling agent, (2) a stabilizer, (3) a lubricant, (4) a non-crosslinkable film-forming polymer and (5) a cross- linkable film-forming polymer. The resulting sized glass fibre strands have been found, to be storage stable; to form a package of sized glass fibre which is readily available for subsequent use; and to show improved adhesion when used as filler for polymeric material. Many materials are listed but in the preferred embodiment (1) is gamma- amino propyl triethoxy silane, (2) is cis-butene-dioic acid, (3) is a maleonated amorphous polypropylene (4) is a vinylacetate homopolymer, and (5) is a vinylacetate- methylolacrylamide. |
