摘要： An open-cell polystyrene foam is provided which is formed from a blend of polystyrene and an ethylene-styrene interpolymer. The ethylene-styrene interpolymer functions as a cell opening agent, and is used to control the open cell content of the resulting foam, which may contain greater than 80 percent open cells. The foam is produced by an extrusion process in which carbon dioxide is used as the preferred blowing agent. The resulting foams may be formed into beads, plank, round, sheets, etc.

摘要： A low density foam having a density less than 15 pounds per cubic foot (240 kg/m.sup.3) is formed from an amorphous polyethylene terephthalate polymer. An expandable resin composition is also disclosed, comprising an amorphous polyethylene terephthalate polymer and a blowing agent mixture comprising a low permeability blowing agent and a high solubility blowing agent. Unexpanded and partially expanded foam particles, impregnated with the blowing agent mixture are disclosed. Numerous methods are disclosed for producing lightweight foams from amorphous polyethylene terephthalate polymers. One such method utilizes an Accumulating Extrusion Expansion System which avoids problems experienced with the prior art when attempting to extrusion expand polyesters.

摘要： An expandable ethylenic or styrenic polymer composition for production of lightly crosslinked foamed polymers and a process for controlling the degree of crosslinking of the polymer prior to extrusion foaming. The control is obtained by use of (a) a reversible gas-yielding crosslinking reaction which is delayed in the foam extrusion line in the presence of gaseous products (alcohols) and (b) added amounts of an alcohol such as an aliphatic alcohol. Suitable crosslinking agents include silanes, azido functional silanes, titanates, and amino compounds.

摘要： This invention pertains to a composition and a process for preparing a closed cell alkenyl aromatic polymer foam having enlarged cell size, comprising one or more alkenyl aromatic polymers, one or more substantially random interpolymers, one or more blowing agents having zero ozone depletion potential and optionally one or more co-blowing agents, and optionally, one or more nucleating agents and optionally, one or more other additives.This combination allows the manufacture of closed cell, low density alkenyl aromatic polymer foams of enlarged cell size, when blowing agents of relatively high nucleation potential are employed. When such blowing agents are used with alkenyl aromatic polymers in the absence of the substantially random interpolymers, small cell foams result.
