Abstract
Abstract A sheet pallet having improved properties is molded using a thermoplastic resin composition containing a partially crosslinked product which is obtained by dynamically heat-treating: (A) a thermoplastic resin, and/or (B) a rubbery substance, in the presence of a crosslinking agent and, if desired, a polyfunctional monomer, the said sheet pallet having a loading surface whose frictional coefficient is larger than that of the back side thereof, and also having a thickness of 0.3 to 10 mm.
