Abstract: A polymer sheet having a decorative surface and a nondecorative surface may be joined to a thermoplastic “substrate” by melt bonding the nondecorative surface and a surface the substrate to different sides of a sheet which has two irregular surfaces. The resulting article is useful for products where a decorative surface on a thermoplastic substrate is desirable, such as automobiles, appliances and power tools.

Abstract: A compound for a composite body having a hard and a soft component, and to a process for producing such a composite body is provided. The compound comprises a hard component (a) of a polyoxymethylene and a soft component (b) of one or more hydrogenated styrene block copolymers, molded directly onto component (a). The styrene block copolymers are from the group of poly-isoprene/butadiene polymer (SEEPS), poly-isoprene polymer (SEPS); poly-butadiene polymer (SEBS), and combinations thereof. The styrene block copolymer is adhesion-modified by the addition of a compound selected from styrene/butadiene copolymer (SBS); ethylene/vinyl acetate copolymer (EVA); olefinic polymers, polystyrene (PS), and combinations thereof.

Abstract: Differing thermoplastics may be joined by melt bonding a thermoplastic to one side of a resin sheet having irregular surfaces and melt bonding a different thermoplastic to the other side of the sheet. The bonds obtained are often very strong, resulting in cohesive failure of one of the thermoplastics when one attempts to pull apart the thermoplastics.

Abstract: This invention relates a method for forming a polyacetal blend substrate having at least one discontinuous or co-continuous layer adhered thereon, wherein the method utilizes concentrates to deliver the polymers that provide enhanced surface adhesion.

Abstract: The present invention relates to layered articles comprising (a) a substrate comprising 99.5-40 weight percent of an polyoxymethylene polymer; and 0.5-60 weight percent of at least one non-acetal thermoplastic polymer; and (b) at least one additional layer deposited thereon.
