  • Publication number: 20050222425
    Abstract: Described in this invention is a catalytic process for making amide acetals from nitrites and diethanolamines. Amide acetals can be further crosslinked by hydrolyzing the amide acetal groups, and subsequently reacting the hydroxyl groups and/or the amine functions that are formed, to crosslink the composition.

  • Publication number: 20050159625
    Abstract: A composition that can be used as a component in auto clear coat and primer is disclosed. The composition comprises or is an alkoxylated amine having the formula of (A)[N(R1H)2]p including an isomer or mixture of isomers thereof. Also disclosed is a process, which comprises contacting an amine with an epoxide under a condition sufficient to produce an alkoxylated amine. Further disclosed is a composition that can be used as coating composition and primer, which comprises an alkoxylated amine and an organic polyisocyanate.

  • Publication number: 20050059737
    Abstract: The present invention is directed to compositions of specific carboxylic acid, fatty acid or oil derivatives containing nitrile groups and methods of their preparation. The preparation involves a hydrocyanation reaction. A method of hydrgenating the nitrile containing carboxylic acid acids obtained by above hydrocyanation to produce amine containing carbixylic acids is also disclosed in this invention.
