Patent number: 5600089Abstract: Elastomers having a polyurethane binder are formed from a mixture including tetrastar polyethylene oxide polyol with a molecular weight of at least 16000 daltons and a plasticizer present in a ratio of at least five parts by weight to one part of the polyol and provide high tensile strength, extreme elongation, great flexibility, and absence of voids. Energetic elastomers use a nitrate ester plasticizer with a curative having a functionality of at least three and an NCO/OH equivalent ratio of about 2.5 and may include an energetic particulate filler. Inert elastomers use a non-volatile ester plasticizer, as dimethyl phthalate, with a curative having a functionality of two and an NCO/OH equivalent ratio not over 2.0.Type: GrantFiled: December 7, 1994Date of Patent: February 4, 1997Assignee: The United States of America as represented by the Secretary of the NavyInventors: Russell Reed, Jr., Vicki L. Brady

Patent number: 5491189Abstract: The adhesive strength of an aqueous binder dispersion consisting of: a halogenated copolymer which, in addition to other components, contains an alkylation-active monoalkenylaromatic alkyl halide; polyfunctional aromatic nitroso compounds; pigments; carbon black; anti-foaming agents; emulsifiers; and other additives, used for vulcanizing rubber onto substrates which are stable under the conditions of vulcanization, is improved, and the use of blocked isocyanates is avoided. This is achieved by adding, to increase the adhesive strength, homopolymers or copolymers of vinyl acetate that are also saponified to a certain extent, as well as, optionally, other customary additives.Type: GrantFiled: January 26, 1994Date of Patent: February 13, 1996Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Hans Scheer, Wolf-Dieter Beiersdorf, Hans-Joachim Purps
