Abstract:
A composition comprising a silyl-containing copolymer wherein said copolymer comprises:(a) Monomer (A) shown by the following Formula (I): ##STR16##as a silyl-containing monomer and wherein R.sub.1, is a hydrogen atom or methyl group; R.sub.2 is an alkylene group having 1-6 carbon atoms; and R.sub.3, R.sub.4 and R.sub.5 each is a reactive functional group which can cross-link molecules of the copolymer by hydrolyzing;(b) Monomer (B) shown by the following Formula (II): ##STR17##wherein R.sub.6 is a hydrogen atom or methyl group; R.sub.7 is an alkyl group having 1-18 carbon atoms;(c) Monomer (C) shown by the following Formula III: ##STR18##wherein R.sub.8 is a hydrogen atom or methyl group; R.sub.9 is an alkylene group having 1-6 carbon atoms; and X is a group expressed by any of the following Formulae (IV) to (VI): ##STR19##wherein R.sub.10 is an alkyl group having 1-6 carbon atoms; ##STR20##wherein R.sub.11 and R.sub.11' each is an alkyl group having 1-6 carbon atoms; and X1 is an integer of positive number; and ##STR21##wherein R.sub.8 and R.sub.9 are the same as defined in Formula (III); R.sub.12 is an alkyl group having 1-6 carbon atoms; and X2 is and integer of positive number; and(d) Monomer (D) shown by the following Formula (VII): ##STR22##wherein R.sub.13 is a hydrogen atom or methyl group; R.sub.14 is an alkylene group having 1-6 carbon atoms; and y is a group expressed by --N.sup.+ (R.sub.15).sub.3 or --N(R.sub.15).sub.2, wherein R.sub.15 is an alkyl group having 1-6 carbon atoms;and wherein the percentage of Monomer (A) is at least about 25 wt % of the copolymer.
