| 21 | Adhesive system for bonding uncured rubber to cured polyurethane | US242392 | 1988-09-09 | US4942093A | 1990-07-17 | David F. Lawson |
| A thermosetting adhesive comprising a bismaleimide compound and an isocyanate-terminated rubber polymer adapted to coreact upon heating is applied to substrate surfaces of a cured polyurethane and an uncured rubber compound. Upon heating, the adhesive crosslinks and the uncured rubber compound is preferably cured simultaneously. The adhesive is particularly useful in the fabrication of compositions by the bonding of cured polyurethane to an uncured rubber compound which becomes cured during the bonding process, such as in the construction of tires containing cured polyurethane reinforcements within uncured rubber carcasses, the retreading of tires containing polyurethane repairs, etc. | ||||||
| 22 | Two stage process for the production of molded articles | US131959 | 1987-12-11 | US4788224A | 1988-11-29 | Hanns P. Muller; Walter Uerdingen; Heinrich Heine |
| Molded articles are produced in a two-stage process. In the first stage, an organic polyisocyanate is reacted with an organic compound containing at least two epoxide groups (NCO: epoxide equivalent ratio of 1.2:1 to 500:1) in the presence of a tertiary amine catalyst. This reaction is stopped when no more than 65% of the isocyanate groups have reacted by adding an alkylating sulfonic acid alkyl ester of methyl iodide and/or of dimethyl sulfate in an amount equivalent to the amount of tertiary amine catalyst present. A latent catalyst capable of being activated by heat is subsequently added to the intermediate product and the resultant mixture is heated in a mold to complete the crosslinking of the intermediate product and to form the molded article. | ||||||

| A thermosetting reactive resin mixture is made from an organic polyisocyanate, a polyepoxide and a heat activatable catalyst. The catalyst is a tertiary or quaternary ammonium salt of an alkylating or acidic ester of an organic phosphonic acid or of phosphoric acid. The polyisocyanate and polyepoxide are used in quantities such that the equivalent ratio of isocyanate groups to epoxide groups is from 1.2:1 to 70:1. These mixtures may be heated to produce plastics having excellent heat resistance, moisture and abrasion resistance, low dielectric losses and excellent molding properties. | ||||||

| This invention is concerned with autoxidizable coating compositions which contain(1) a member of the group consisting of an organic polyisocyanate, an isocyanate-modified drying oil, and a uralkyd;(2) at least one non-volatile reactive liquid monomer selected from the group consisting of dicyclopentenyloxyalkyl acrylate and dicyclopentenyloxyalkyl methacrylate; and(3) an effective amount of a polyvalent metal-containing complex or salt that catalyzes the curing of (1) and (2).Use of the non-volatile reactive liquid component enables the production of coating compositions having high application solids content and yet having suitable viscosity for efficient handling. The reduced volatile component improves the environmental aspects of preparing and using the coating compositions while the combining of these materials in the film results in enhancement of the film properties without detriment to the qualities normally desired and attained with the polyurethane type of coating composition. | ||||||
