  Thermoplastic, crosslinkable copolymer is produced by reacting an active-hydrogen containing initiator with a lactone monomer, such as epsilon-caprolactone, and a polyfunctional acrylate, such as neopentyl glycol diacrylate. The copolymer can be crosslinked by exposure to ionizing or actinic radiation or by free-radical peroxide catalysts. The degree of crosslinking can be controlled to produce a material which is thermoplastically processable and displays modified rheological properties which make it more easily processable than the corresponding lactone homopolymer.

  热塑性可交联共聚物是通过含活性氢的引发剂与内酯单体（如epsilon-caprolactone）和多官能丙烯酸酯（如新戊二醇二丙烯酸酯）反应制得的。共聚物可以通过电离辐射或光辐射或自由基过氧化物催化剂进行交联。通过控制交联度，可生产出可热塑性加工的材料，并显示出改良的流变特性，使其比相应的内酯均聚物更易于加工。
