In addition to the amino silane coupling agent, the sizing composition may have an epoxy silane coupling agent and/or a lubricant modified silane coupling agent. The wax can be deleted from the composition, when the polyethylene-containing polymer has limited branching. The sized glass fiber strands can be produced by conventional forming process or by a wet chopped glass fiber forming process.
