SILANE END CAPPED SUBSTITUTED UREA RESINS AND COATINGS THEREOF

摘要

The compound below. R¹ is an alkyl group or -(SiR⁷₂-O)_m-R⁸. R⁷ is an alkoxy group. The value m is a nonnegative integer. R⁸ is an alkyl group or R³ and R⁴ are organic groups. R⁵ is an aliphatic group or a residue of a homopolymer of an aliphatic polyisocyanate. R⁶ has an electron withdrawing group that is bound to a carbon atom that is bound to the CHR⁴ group. The value n is an integer greater than or equal to 2. A method of: reacting a 3-trialkoxysilylpropyl amine with an organic compound having a carbon-carbon double bond activated by an electron withdrawing group to form a secondary amino propylalkoxysilane, and reacting the secondary amino propylalkoxysilane with an aliphatic polyisocyanate or a polymer thereof.
