Filed:

Mar 7, 2008

Appl. No.:

12/044714

Inventors:

Eric J. Lind - Naperville IL, US
Christine S. Fouts - Wadsworth IL, US

Assignee:

Petroferm, Inc. - Fernandina Beach FL

International Classification:

B32B 17/10
C08F 299/08

US Classification:

428429, 526279

Abstract:

Polyoxyalkylene siloxane copolymer compositions and their application as antistatic agents to fiberglass insulation, textile, plastic, fiber optic, and electronics substrates are described. The polyoxyalkylene siloxane copolymer composition is made by the free radical polymerization of a vinyl polyoxyalkylene siloxane monomer with one or more organic unsaturated monomers. The vinyl polyoxyalkylene siloxane monomer has a linear, branched, or cyclic structure that may or may not be crosslinked. Aqueous solutions of the polyoxyalkylene siloxane copolymers provide improved wetting and uniform coverage on substrates. Treatment of fiberglass insulation with the polyoxyalkylene siloxane copolymers of the invention leads to improved antistatic properties and R-values.

International Classification:

C08G 1814

US Classification:

521137

Abstract:

Polyurethane systems are disclosed utilizing polyvinyl acetate/allyl alcohol random copolymers to produce rigid polyurethane foams and a process for producing the same. The resulting foams exhibit improved K-factors, utilized reduced amounts of fluorocarbons as blowing agents, and maintained insulating properties when formulated with increased amounts of water.

International Classification:

C08J 928

US Classification:

521 53

Abstract:

A carboxylic containing superabsorbent polymer having a swell rate of at least 0. 3 g. /g. sec. , a gel strength of about 40,000 to about 150,000 dynes/cm. sup. 2, a centrifuge capacity at 30 minutes of about 20 to about 50 g/g, an absorption permeability under pressure at 60 minutes of at least 5 g/g at wherein the ratio of the absorption permeability under pressure at 15 minutes is at least 25% of the absorption permeability under pressure at 60 minutes is disclosed. The superabsorbent polymer is prepared from a solution of carboxylic containing monomers, a cross linking agent, and a blowing agent. The polymer is subsequently treated with a surface crosslinking agent.

US Classification:

521 53

Abstract:

A superabsorbent polymer having improved absorption under pressure and fast absorption rate is obtained by first providing a solution containing carboxylic acid monomers or water soluble salts thereof, and a crosslinking agent. A carbonate blowing agent and a polymerization initiator are added, individually or in combination, to the solution to form a carbonated monomer solution. A polymerization initiator is then added to the carbonated monomer solution which is then polymerized at temperatures ranging from about 0. degree. C. to about 130. degree. C. , forming a microcellular hydrogel. The microcellular hydrogel is chopped or ground into gel pieces having a particle diameter ranging from about 0. 1 mm to about 5. 0 cm. The gel pieces are dried at temperatures ranging from about 85. degree. C.

Assignee:

Nalco Chemical Company - Naperville IL

International Classification:

L08J 908

US Classification:

521 92

Abstract:

An improved superabsorbent polymer having increased rate of water absorption is obtained by the addition, preferably prior to polymerization, of a carbonate blowing agent to a monomer solution of the monomers used to form the superabsorbent polymer. Preferred monomers include (meth)acrylic acids, preferably partially neutralized prior to polymerization and appropriate cross-linking agents. The carbonate cross-linking agents are any carbonate salt soluble or dispersible in the monomer solution, prior to polymerization. The multi-valent cationic salts of carbonate are preferred, especially the complex carbonates, for example, of magnesium.
