The invention relates to thermoplastic polyolefin compositions having enhanced surface durability and products thereof which include a thermoplastic polyolefin base component at least one radiation-polymerizable component present in an amount sufficient to enhance the surface durability of the thermoplastic polyolefin component when radiation-cured and at least one photoinitiator present in an amount sufficient to initiate crosslinking of the radiation-polymerizable component upon exposure of the thermoplastic polyolefin composition to radiation. The invention further relates to methods of providing a cured thermoplastic polyolefin composition having enhanced surface durability by preparing a mixture having a thermoplastic polyolefin base component, at least one radiation-polymerizable component, and at least one photoinitiator, and then exposing the thermoplastic polyolefin composition to radiation thereby providing a thermoplastic polyolefin composition having enhanced surface durability.
本发明涉及具有增强表面耐久性的热塑性聚烯烃组合物及其产品,该组合物包括热塑性聚烯烃基体组分,至少一种可辐射聚合组分,其含量足以在辐射固化时增强热塑性聚烯烃组分的表面耐久性,以及至少一种光
引发剂,其含量足以在热塑性聚烯烃组合物暴露于辐射时引发可辐射聚合组分的交联。本发明进一步涉及通过制备具有热塑性聚烯烃基组分、至少一种可辐射聚合组分和至少一种光
引发剂的混合物,然后将热塑性聚烯烃组合物暴露于辐射,从而提供具有增强表面耐久性的固化热塑性聚烯烃组合物的方法。
