Polyolefin materials having enhanced surface durability and methods of making the same by exposure to radiation

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.
