  • Patent number: 8563664
    Abstract: A composition, prepolymer and method to produce a polymer based on biodegradable or essentially renewable crude materials, which can be crosslinked by free radicals. The composition is based on polyesters that are functionalized with unsaturated monomer units, in a way that unsaturated groups can be located along the polymer main chain as well as at the ends of the prepolymer. In connection to the product production, the prepolymer is exposed to free radicals that leads to network formation. The composition of the crosslinked biopolymer can be adjusted from a stiff engineering material to an elastic rubbery material. The new biopolymer can be used in composite materials, dispersions, barrier materials, rubbery materials, biomedical applications, and the like.

  • Patent number: 6545092
    Abstract: 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.

  • Patent number: 4370447
    Abstract: An unsaturated polyester was obtained by reacting a polyhydric alcohol with a mixture of an unsaturated polybasic acid and a specific saturated dibasic acid represented by the formula: ##STR1## or the formula: ##STR2## wherein, R.sub.1 to R.sub.10 are each hydrogen or alkyl, R' to R"" are the same or different and each represent hydrogen or ester-exchangeable alkyl, m is 1 or 2, and n is zero or 1. The compositions comprising this polyester and an aromatic vinyl monomer, when hardened in the presence of a catalyst, exhibit a lower shrinkage during the hardening and give molded products with improved resistance to alkalis and to boiling water.

  • Patent number: 4359570
    Abstract: Disclosed are colored polyester compositions containing copolymerized anthraquinone dyes as colorants, which compositions may be used, for example, for food packaging and to mold colored beverage bottles. The copolymerized dyes are thermally stable at the processing temperatures, and are colorfast and nonextractable. The useful dyes have the general formula: ##STR1## wherein either or both of rings A and B may contain in any position thereon one or two groups of the formula ##STR2## R and R.sup.3 each is hydrogen, lower alkyl or lower hydroxyalkyl; R.sup.1, R.sup.2, R.sup.4 and R.sup.5 each is hydrogen or 1-3 substituents such as lower alkyl, lower alkoxy, phenyl, Cl, Br, or the like; X is --S-- or --NH--; n is 1 or 2; m is 0, 1, or 2.

  • Patent number: 4354007
    Abstract: 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.

  • Patent number: 4304879
    Abstract: 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.

  • Patent number: 4281074
    Abstract: 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.
