Abstract
Cross-linked thermoplastics articles are fabricated by providing a radiant energy-crosslinkable thermoplastics sheet, masking areas of the sheet, exposing the masked sheet to appropriate radiant energy, fusing the masked and relatively uncrosslinked areas together under heat and pressure, and locally applying crosslink inducing energy to the fused portions.
