Abstract: Foamed reactor made thermoplastic polyolefins (rTPOs), and articles made therefrom, are described. The compositions have an rTPO combined with a foaming agent. The foaming agent can be a physical blowing agent and/or a chemical foaming agent, and may include optional nucleating agents. Some compositions utilize a masterbatch having one or more chemical foaming agents to foam the rTPOs. The rTPOs have a large melt flow rate range and flexural modulus range that translate into a broad scope of potential applications and foamed architecture. This allows the combination of rTPOs and foaming agents to be fine-tuned for selected foaming application.

Abstract: Foamed propylene-based reactor made polyolefins, and articles made therefrom, are described. The compositions have a resin that is a reactor made propylene based random copolymer or terpolymer with high comonomer content, combined with a foaming agent. The foaming agent can be at least one physical blowing agent or at least one chemical foaming agent, and may include optional nucleating agents. Reactor made copolymers and terpolymers have a large range of high comonomer content and therefore have physical properties such as increased flexibility, high gloss, lower sealing temperature, and improved compatibility with other polyolefins. These properties translate into a broad scope of potential applications and foamed architecture. This allows the combination of the copolymer or terpolymer, and foaming agents to be fine-tuned for selected foaming application.

Abstract: Resistance to cathodic or galvanic disbondment of plastic-metal laminates is obtained by incorporating in the metal bonding plastic material used in forming the laminate an amount of conductive carbon black effective to minimize or prevent disruption of the bond by galvanic action which otherwise would take place in the absence of the conductive carbon black. The conductive carbon black is used in a relatively high concentration, for example, between about 20 and about 40 percent, with the balance of the composition being made up of a polymeric material containing an amount effective to promote bonding between the metal and the polymeric material of an ionomeric copolymer containing about 25 to about 98.5 percent ethylenic units and between about 1.5 to about 30 percent carboxylic acid units, the major proportion of which is in the free acid form. Advantageously, two-thirds or more of the carboxylic units are in the free form and the remainder, if any, are neutralized by zinc.
