    Patent number: 4043555
    Abstract: A filamented polymer material of standard compounding, originally extruded or vertically drawn to a uniform diameter and having typical strength and resiliency characteristics, is converted to a material having increased resiliency characteristics simulating those of catgut and lamb gut for use in tennis racquets. The method for the conversion comprises subjecting a filament or a plurality of twisted together filaments of the material to irradiation, which causes a crosslinking of its molecules.
