Abstract:
A composition comprising repeat units derived from (a) a carbonyl compound or oligomer thereof, (b) a glycol, and (c) a crosslinker whereinsaid carbonyl compound is HOâ€”R1â€”COOH or R1O2CACO2R1; A is an alkylene group, arylene group, alkenylene group, or combinations of two or more thereof having 2 to 30 carbon atoms per group; each R1 is independently selected from (i) hydrogen, (ii) a hydrocarboxyl radical having a carboxylic acid group at the terminus, or (iii) a hydrocarbyl radical in which each radical has 1 to 30 carbon atoms per radical selected from an alkyl, alkenyl, aryl, alkaryl, aralkyl radical, or combinations of two or more thereof; said oligomer has 2 to 100 repeat units; said crosslinker is a glycol-organosilane, which comprises or is produced by combining (a) a glycol and (b) an organosilane comprising DmSiXnZp; D is a halogen, a hydrogen, or a hydrocarbon oxygen group; X is a hydrocarbon or a hydrocarbon oxygen group; Z is a reactive hydrophobic group; each of m and n is 1 to 3; and p is 1 to 20.
