摘要： Expanded products, more specifically, rigid or semi-flexible foams of low density from 1.5 to 12 lbs/ft3 or more, with closed cells can be manufactured. The products have a PVC backbone with branches with methacrylate crosslinked with isocyanate through a reaction activated by ultraviolet or microwave radiation. The use of polyfunctional monomers that are sensitive to irradiation yields a higher cross-link density, which improves the physical and mechanical properties such as hardness, resistance to abrasion, ductility, and resistance to friction. The selection of monomers and oligomers allows the manufacturer to determine of the final properties of the foam. The process yields foams with extreme hardness and better shear factors making the foam an ideal product for aerospace and windmill use. These physical properties emerge during the post-curing process, preferably by use of compounds based on methacrylates in dispersion with PVC and isocyanates.

摘要： An emulsion or suspension polymer comprising a vinyl chloride polymeric core and an acrylic ester-acrylonitrile polymeric shell is disclosed. The emulsion polymer is preferably prepared using a two-stage process. In the first stage, a vinyl chloride monomer is polymerized or copolymerized to form a first phase of a polymeric hard core having a relatively high chlorine content. In a second stage, the soft acrylic ester-acrylonitrile copolymer is made in situ in a reaction mixture comprising the first phase. The product provides both flame retardancy and low MFFT, and is useful in a variety of coating and binding applications.

摘要： A supercritical graft copolymerization process is described which includes the steps of: adding a polymer into a high pressure reactor; adding a free radically polymerizable monomer into the reactor; adding a free radical polymerization initiator; adding a sufficient amount of a supercritical solvent to dissolve at least a portion of the polymer and the monomer when supercritical conditions are achieved inside the reactor; and heating and pressurizing the reactor to achieve supercritical conditions therein for a time sufficient to effect a graft copolymerization on the polymer by the polymerizing monomer which forms at least one side chain on the polymer. In general, the reaction pressure will range from 70 atm. to 200 atm. and the reaction temperature will range from 50.degree. C. to 90.degree. C. In the examples provided above, the supercritical solvent was carbon dioxide. However, there is no need to limit the application to such in that the process steps will be equally applicable to other supercritical solvents which have the ability to dissolve at least a portion of the polymer and grafting monomer when at supercritical conditions in the reactor. In general, the reaction time will range from one to six hours, although shorter and longer reaction times are contemplated within the scope of this invention, the range merely being listed as the best mode known to the inventors at the time of the filing of this application. Specifically, the graft copolymerization process has been demonstrated when the polymer is a polyolefin, particularly polypropylene and poly(vinyl chloride), although other backbone polymers are certainly contemplated as within the scope of this invention. Specific examples are discussed wherein the monomer used to effect the graft copolymerization are selected from the group consisting of styrene and acrylic acid when the polyolefin polymer is polypropylene and also specifically discussed is a poly(vinyl chloride) polymer wherein the grafted polymer is based on a monomer of vinyl acetate.
