A method of producing a laminated body, the method including a coagulant solution deposition step of depositing a coagulant solution on a fiber substrate, and a coagulation step of forming a polymer layer on the fiber substrate by bringing a polymer latex into contact with the fiber substrate having the coagulant solution deposited thereon to cause a polymer to coagulate. As the coagulant solution, a solution obtained by dissolving or dispersing 0.2 to 7.0% by weight of a metal salt as a coagulant and 0.1 to 7.0% by weight of an organic acid in a solvent is used. In the method of producing a laminated body, the metal salt is a polyvalent metal salt. In the method of producing a laminated body, the organic acid is an organic acid having at least one group selected from a carboxyl group, a sulfo group, a hydroxy group, and a thiol group.

The present invention relates to a method of preparing a thermoplastic resin. More particularly, the present invention relates to a method of preparing a thermoplastic resin, the method including A) a step of coagulating an emulsion-polymerized latex with an acid; B) a step of treating the coagulated aggregate (slurry) with a base, followed by dehydration; and C) a step of treating the dehydrated wet powder with an acid, followed by dehydration. A method of preparing a thermoplastic resin which exhibits reduced gas generation, color improvement, and superior thermal stability is provided.

This application relates to synthetic elastomeric articles, such as gloves, comprising the cured product of a synthetic latex composition, the synthetic latex composition comprising a synthetic carboxylated polymer and a cross-linking composition, the cross-linking composition comprising an aqueous solution of a negatively charged multivalent metal complex ion having a pH of at least 9.0. Also described are compositions for forming the articles, and methods for making the articles, based on the use of the described cross-linking composition. The articles, compositions and methods contain a second cross-linking agent comprising either (a) sulphur and a sulphur donor, (b) a multivalent metal oxide or ionic cross-linking agent, (c) sulphur, a sulphur donor and an ionic cross-linking agent, or (d) sulphur donor.

An elastomeric article is formed from a blend of nitrile rubber and polychloroprene rubber. The elastomeric article can be a glove, such as a medical exam glove. The elastomeric article is softer than a conventional nitrile elastomeric article. The elastomeric article is formed from a blended rubber latex emulsion of nitrile and polychloroprene. The blended rubber latex emulsion may be free of sulfur and vulcanization accelerators.

Disclosed are aromatic enol ethers that have utility as film-hardening additives for coating formulations. The aromatic enol ethers have particular utility as film-hardening additives for water-based coating formulations. The aromatic enol ethers provide improvements in hardness and hardness related properties such as block resistance without contributing to the volatile organic content of the composition.
