Abstract
A moisture-curable silicone resin formed from reaction of a silylated polyethyleneimine, an acid or a base, and at least one hydrolyzable silane having formula R1nSiR24-n, wherein R1 is alkyl, aryl, fluoroalkyl, trialkylsilyl, triarylsilyl, vinyl, or a combination thereof; R2 is alkoxy, aryloxy, acetoxy, oximino, enoxy, α-hydroxycarboxylic acid amide (—OCR2CONR2), α-hydroxycarboxylic acid ester (—OCR2COOR), H, halogen, or a combination thereof; n=0, 1, 2, or 3; R is alkyl or H. A process for preparing a moisture-curable silicone resin includes reacting an acid or a base, the at least one hydrolyzable silane having formula R1nSiR24-n, silylated polyethyleneimine, and heating the mixture.
