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-crosslinkable 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-crosslinkable
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-crosslinkable component in an amount sufficient to
enhance the surface durability of the polyolefin when radiation cured, and
at least one photoinitiator each in an amount sufficient to facilitate
crosslinking of the radiation-crosslinkable component when a surface of
the thermoplastic polyolefin composition is exposed to radiation, and then
exposing the thermoplastic polyolefin composition to radiation in an
amount sufficient to crosslink the radiation-crosslinkable component
thereby providing a thermoplastic polyolefin composition having enhanced
surface durability.
