Crosslinkable compositions are provided that contain a) a polymeric material having at least two terminal dithiocarbamate groups or two terminal dithiocarbonate groups and b) a monomer composition that includes at least a crosslinking monomer having two or more ethylenically unsaturated groups. The polymeric materials in the crosslinkable compositions undergo chain extension and crosslinking reactions when exposed to actinic radiation in the ultraviolet region of the electromagnetic spectrum. Additionally, crosslinked compositions, articles that contain the crosslinkable compositions or the crosslinked compositions, and methods of making the articles are provided.
可交联组合物包含 a) 具有至少两个末端二
硫代
氨基甲酸酯基团或两个末端二
硫代
碳酸酯基团的聚合材料和 b) 单体组合物,该单体组合物至少包括具有两个或两个以上
乙烯基不饱和基团的交联单体。可交联组合物中的聚合材料在暴露于电磁波谱紫外区的光辐射时会发生链延伸和交联反应。此外,还提供了交联组合物、含有可交联组合物或交联组合物的物品以及制造这些物品的方法。
