Patent number: 4617373Abstract: Molding or fiber grade condensation polymer having copolymerized therein a total of from 1.0 to about 5,000 ppm of at least one methine moiety having one or more methine units defined as "the group >C.dbd.C< conjoined with a conjugated aromatic system," said moiety absorbing in the range of from about 350 nm to about 650 nm, and being nonextractable from said polymer and stable under the polymer processing conditions. The moieties preferably have molecular weights of from about 200 to about 600 although lower and higher molecular weights are also operable and are derived from reactants (monomers) having one or more groups such as hydroxyl, carboxyl, carboxylic ester, acid halide, amino and the like which condense during condensation or polycondensation to enter the moiety into the polymer chain.Type: GrantFiled: January 28, 1986Date of Patent: October 14, 1986Assignee: Eastman Kodak CompanyInventors: Wayne P. Pruett, Richard H. S. Wang, Samuel D. Hilbert, Max A. Weaver

Patent number: 4569985Abstract: There is disclosed a group of poly(ester-amide) compositions which possess unexpectedly good low temperature adhesive properties with respect to vinyl based substrates. These poly(ester-amide) compositions are the reaction product of a polymeric fatty acid, with an organic diamine, dicarboxylic acid and an alkanolamine having the general formula: ##STR1## wherein R.sub.2 represents alkylene of 2 to 8 carbons, and R.sub.1 is selected from the group consisting of hydrogen and a monovalent moiety of the formula:R.sub.3 --CH.sub.2 --CH.sub.2 -- (II)wherein R.sub.3 is selected from hydroxyl and amino groups.The term "alkylene of 2 to 8 carbons" as used throughout the specification and claims means a divalent moiety of the formula: ##STR2## wherein n is an integer of from 0 to 6. N-(2-hydroxyethyl)piperazine is a preferred compound of the alkanolamine group.Type: GrantFiled: August 2, 1985Date of Patent: February 11, 1986Assignee: Union Camp CorporationInventors: Charles R. Frihart, Richard L. Veazey

Patent number: H365Abstract: Poly(diethylene glycol-4,7-dinitrazadecane-dioate), P-DEND), is synthesized y the Michael addition of ethylene dinitramine to methyl acrylate to yield the intermediate compound dimethyl-4,7-dinitrazadecane-dioate (DMDND). DMDND is reacted for a period of about 18 hours with diethylene glycol (DEG) at about 85.degree. C. in presence of a p-toluenesulfonic acid catalyst to yield P-DEND. The product (P-DEND) is purified by passing it through a silica gel column using methylene chloride as solvent. The average molecular weight of P-DEND ranges from about 1500-2000. P-DEND is shown to be compatible with stabilized nitroglycerin for use as an energetic polymer binder for high performance propellants.Type: GrantFiled: January 29, 1987Date of Patent: November 3, 1987Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Minn-Shong Chi
