1. A raw material that constitutes the reaction product of two compounds (1) and (2) having the general formulas (1) and (2), wherein the first compound (1) has the general formula
R1—(CH2)a—(CHR2)b—(CR32)c—(CHR4)d—(CH2)e—R5 (1) where R1, R2, R3, R4 and R5, independently of one another, are each an OH, NH2, NHR′ and/or SH reactive group, and R′ is a linear or branched alkyl chain having 1 to 10 carbon atoms, an alkaryl or aralkyl group having 6 to 10 carbon atoms, or an aryl group having 5 to 10 carbon atoms, and a, b, c, d, and e can each be 0 or an integer between 1 and 10, with the condition that the sum of a+b+c+d+e is an integer greater than 1; and the second compound (2) has the general formula
Y-A-Si(OR1)r(R2)3-r (2) where Y is NCO, Br or Cl, COOH, COCl , an epoxy, aldehyde or acrylate group; A is a linear or branched alkyl chain having 1 to 20 carbon atoms, an alkaryl or aralkyl group having 6 to 20 carbon atoms, or an aryl group having 5 to 20 carbon atoms; OR1 is a hydrolyzable group; R2 is a linear or branched alkyl group having 1 to 6 carbon atoms; and r is a number from 1 to 3. |
