A plastic pallet ( ) having good load bearing construction and held together without mechanical fasteners, includes deck boards ( ). The deck boards include ridges ( ) on an upper side ( ) and a lower side ( ) thereof. Deck boards are positioned transversely on stringers ( ) and joined thereto by either an adhesive or thermoplastic welding processes. The stringers and deck boards may be provided with end caps ( ) which seal interior areas of the stringers and deck boards and prevent tearing thereof. The stringers and deck boards have interior reinforcement ribs ( ). The cross sectional profiles of the stringers, deck boards, and end caps provide a cost effective and light weight pallet. Openings which extend between the stringers allow for either two way fork entry and/or four way fork entry. The stringers and deck boards provide flexibility in constructing pallets of various designs. The plastic pallet preferably is highly durable and fully recyclable.

The present invention relates to electrostatic dissipative impact modified polymeric compositions comprising an effective amount of a chain extended block copolymer, polyvinyl halide and no more than 10 weight parts of a polymeric impact modifier per 100 weight parts of polyvinyl chloride. The chain extended block copolymer is formed from reacting a di-functional polyether with a chain extender which is a condensate selected from the group consisting of polyundecanolactam, polydodecanolactam, poly(11-aminoundecanoic acid) and (12-aminododecanoic acid). The compounds further comprise a heat distortion modifier which does not interfere with ESD properties and is selected from the group consisting of styrene-acrylonitrile copolymer, alpha methyl styrene-styrene-acrylonitrile terpolymer, a polymer of alpha methyl styrene-styrene-N-cyclohexyl maleimide, N-phenylmaleimide, imidized polymethyl methacrylate, post-chlorinated polyvinyl chloride, styrene-maleic anhydride polymer, imidized styrene-maleic anhydride polymer, acrylic-imide copolymer, acrylonitrile-methylmethacrylate copolymer, acrylonitrile-acrylate-polybutadiene graft copolymer, alpha methyl styrene-methylmethacrylate-acrylonitrile terpolymer, alpha-methyl styrene-styrene-methylmethacrylate terpolymer, alpha methyl styrene-methylmethacrylate copolymer, alpha methyl styrene-acrylonitrile copolymer, alpha methyl styrene-methylmethacrylate graft copolymer on polyacrylate rubber, polycarbonate, and brominated polycarbonate.
