Process for the preparation of an expandable vinyl plastisol capable of yielding cellular products containing a nitrogen-based blowing agent and a zinc salt as accelerator of decomposition of the blowing agent. The accelerator, which is preferably zinc chloride, is incorporated in the plastisol in the form of a solution in a liquid carrier. The process results in cellular products consisting of un...

A method for producing cross-linked polyethylene resin foams which comprises mixing a polyolefin resin, a blowing agent and, optionally, a surface active agent containing hydroxyl groups or an acid amide compound under pressure, said polyolefin resin containing a cross-linkable ethylene polymer having on the side chains thereof silyl groups which effect cross-linking upon contact with water; extru...

Layered, fiber-reinforced composites toughened by the use of thermosetting matrix resins including rigid particles are improved in toughness when the particles are porous and formed of a polyamide. The method is particularly effective in improving the toughness of composites based on thermoset matrix resins, and particularly epoxy resins.
