C07D203/12

US Classification:

548962, 524430

Abstract:

The invention relates to a process for reducing the monomeric aziridine content in a polyaziridine forming reaction mixture by adding to the polyaziridine forming reaction mixture an excess of a carbodiimide scavenger wherein the excess is based on the equivalent ratio of scavenger to monomeric aziridine, and to a product obtained by this process and to a coating composition containing the product obtained by the process.

International Classification:

C08G 18/00

US Classification:

528044000

Abstract:

The present invention is directed to a biuret group-containing polyisocyanate composition having an isocyanate functionality of at least 4 prepared by a process comprising reacting a polyisocyanate adduct which a) is prepared from an aliphatic and/or cycloaliphatic diisocyanate; b) has an average isocyanate functionality of at least 2.5, and c) contains isocyanurate groups, with a secondary monoamine at an isocyanate to amine equivalent ratio of from about 4:1 to about 14:1 to incorporate biuret groups into said polyisocyanate. The invention is also directed to a blocked biuret group-containing polyisocyanate composition which is prepared by reacting the biuret-containing polyisocyanate with a blocking agent.

Abstract:

A process for making an article molded of polymeric material, the article featuring photochromic properties is disclosed. To at least a portion of the surface of an article, molded of a composition that contains at least one transparent thermoplastic polymer or a transparent thermosetting composition there is applied a curable weatherable polyurethane coating. At least a portion of the coating is after curing brought into contact with a material system that contains (i) water, (ii) at least one carrier conforming to wherein Ris a radical selected from the group consisting of linear or branched C-Calkyl, benzyl, benzoyl and phenyl, Ris Ror H, n is 2, 3 or 4, and m is 1 to 35; (iii) a photochromic compound and (iv) a diol, under conditions calculated to bring about diffusion of said compound into the cured coating.
