Abstract: The invention pertains to a process for producing a cross-linked polyolefin foam in a continuous process using standard processing equipment without using a moisture cross-linking step after processing. In this method, a vinyl functional silane compound is melt grafted onto a low density polyethylene in the presence of a free radical generator. The resulting silane grafted polyethylene resin is mixed and melted with a blowing agent in a continuous process in the presence of water to form a vinyl functional silane foam.

Abstract: Porous polymers are made by adding biologically active agent and growth substrates (e.g., yeast and sugar, preferably in the presence of water or other suitable fluid) to a polymer forming material, which may be a liquid. The yeast acts on the sugar, forming carbon dioxide gas bubbles. The material is then polymerized so that the gas bubbles create permanent pores within the polymeric material. The polymer can be an epoxy for example. The pores will contain residue of the yeast. Also, porous metals can be made by combining a metal powder with yeast, sugar, and water. The porous metal paste is then sintered. Porous ceramics and semiconductors can be made by combining the yeast and sugar with a ceramic forming liquid such as polysilazane. Polysilazane converts to silica when heated, which helps to bind the ceramic or semiconductor powder particles at a reduced temperature. Biological agents other than yeast (e.g. bacteria, enzymes), and growth substrates other than sugar can also be used.

Abstract: A foaming additive and a catalyst additive may be used to foam polymeric materials having a low melt flow rate. The foaming additive may include a blowing agent and a hydrophilic component, and the catalyst additive may include a catalyst and a hydrophilic component. Since both the blowing agent and the catalyst are initially combined with a hydrophilic component, the blowing agent and the catalyst are able to find each other easier after being added to the polymeric materials. This makes it simple and economical to make low density foamed materials using polymeric materials having a low melt flow rate.

Abstract: A crosslinked olefin elastomer foam has a specific gravity of 0.05 to 0.2, an expansion ratio of 8 to 15, a compression set of 30 to 60% and a tear strength of 1.5 to 2.5 kg/cm. The crosslinked foam is obtained by heating an elastomer composition comprising a specific ethylene/null-olefin copolymer, an organic peroxide, a crosslinking auxiliary and a foaming agent. The crosslinked foam has a high expansion ratio, is free from surface roughening attributed to defoaming, realizes a soft touch, exhibits a low compression set and is excellent in mechanical strength (particularly tear strength) and heat resistance.
