摘要

The compound below. R1 is an alkyl group or -(SiR7 2-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.
