Patent number: 6545092Abstract: This invention relates to a new adhesive coating composition, particularly for use on airbag fabrics, which is composed of a crosslinked blend of a polyalkyl- or polyphenylsiloxane with vinyl functionality and a copolymer of ethylene and methyl acrylate. This coating provides excellent adhesive properties to the coated fabric, in that it restricts the movement, when put under stress, of the yarns constructing that fabric, which are situated adjacent to seams in the fabric. This reduces the effect known in the trade as combing. Fabric treated with this material in the manner described herein, requires a marked increase in the amount of force required for this yarn movement. This distortion of the fabric can be detrimental in an automotive airbag, in that, it may result in the loss of inflating air, and under extreme conditions may result in a seam failure.Type: GrantFiled: December 11, 2001Date of Patent: April 8, 2003Assignee: Milliken & CompanyInventor: Richard Henry Parker

Patent number: 4355136Abstract: Disclosed are compositions comprising a polyester derived from 100 mole % of an acid component and 100 mole % of a glycol component, the acid component comprising about 30-90 mole % of at least one .alpha.,.beta.-ethylenically unsaturated dicarboxylic acid and about 70-10 mole % of a compound containing a cinnamic acid moiety, and the glycol component comprising at least one saturated aliphatic glycol containing from 2 to 10 carbon atoms. These compositions have improved resistance to attack by organic solvents.Type: GrantFiled: January 4, 1982Date of Patent: October 19, 1982Assignee: Eastman Kodak CompanyInventors: John R. Dombroski, Fred W. Light, Jr.

Patent number: 4354007Abstract: Polymers are rendered more oxidatively stable by reaction with an antioxidant or stabilizer, generally a vinyl-group- or thiol group-containing antioxidant, in the presence of a free radical which may be produced by a redox system or ultra-violet light. The resulting polymers can be used as such or can be used as additives in other polymers to stabilize the latter.Type: GrantFiled: January 14, 1980Date of Patent: October 12, 1982Inventor: Gerald Scott

Patent number: 4304879Abstract: A family of non-crystallizing acrylated polyester resins are described in which the polyesters are formed by reacting a mixture of 100 mol percent dicarboxylic acids of which 50 to 100 mol percent is isophthalic acid; 0 to 25 mol percent is terephthalic acid; and 0 to 50 mol percent is one or more dicarboxylic acids other than isophthalic or terephthalic; with an excess of two or more primary glycols, the maximum mol percent of any one glycol being dependent on the amount of isophthalic acid with the upper limit being established by the line A-B of the FIGURE of the Drawing.Type: GrantFiled: October 20, 1980Date of Patent: December 8, 1981Assignee: Armstrong World Industries, Inc.Inventors: Wendell A. Ehrhart, David A. Smith

Patent number: 4281074Abstract: In the first stage a mixture of a crude diene adduct of 2-naphthol with maleic anhydride is polycondensed at a temperature within the range from 180.degree. to 200.degree. C. with excess glycol or with a dihydric aromatic alcohol, from 0.1 to 3 moles of the alcohol being used per 1 mole of the adduct. In the second stage, the thus obtained product is condensed at a temperature within the range from 160.degree. to 210.degree. C. with an unsaturated acid or the anhydride thereof and with the addition of an equimolar quantity (with respect to the acid or its anhydride) of glycol and/or a dihydric aromatic alcohol. The resulting product is then dissolved in styrene and copolymerized to obtain a cured polyester resin. Propylene glycol, diethylene glycol, dipropylene glycol or butylene glycol may be used as the glycol. The C.sub.2 or C.sub.Type: GrantFiled: February 26, 1980Date of Patent: July 28, 1981Assignee: Polska Akademia Nauk, Zaklad PolimerowInventors: Zbigniew Jedlinski, Antoni Kotas, Boleslaw Ryndak, Stanislaw Mazur, Jan Czarnecki, Mieczyslaw Walkowicz, Stanislaw Jedlinski
