    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: A process for the production of expanded beads, including kneading a base resin containing a polypropylene resin and having a tensile modulus of at least 1,200 MPa together with a mixture of a coloring agent and a thermoplastic polymer having a tensile modulus lower than that of the base resin to form a kneaded mixture including a matrix of the base resin and a multiplicity of domains dispersed in the matrix and each containing the thermoplastic polymer and the coloring agent. The kneaded mixture is formed into resin particles, then treated with an organic peroxide to modify surfaces of the resin particles therewith. Foaming and expanding of the surface-modified resin particles gives expanded beads having an inside region surrounded by a surface region. The heat of fusion of a high temperature peak of the surface region is lower than that of the inside region.

    Abstract: Methods of forming epoxy-based foams include reacting at least one sulfonyl hydrazide chemical blowing agent with at least one curing agent at a temperature between 1° C. and about 60° C. Illustratively, the curing agent is an emulsion of an adduct of a polyamine. A low density ambient cured, non-exothermic, closed cell epoxy foam may be formed for use as an insulation. This insulation may be fire retardant or fire resistant. The foam may be applied as a liquid material which then foams under ambient temperatures and pressures, or as a panel which has been pre-cast, and delivered in a slab form. Densities as low as 0.24 g/cm3 (15 lbs./ft3) can be achieved at 24° C. with compressive strengths approaching 1500 psi.
