Synthetic resin aqueous dispersion

Abstract

Abstract PURPOSE:To obtain the titled dispersion of great cohesive force with improved adhesivity, by incorporating an emulsion from alkyl(meth)acrylate and thiol compound with a reaction product from two sorts of ethylenic unsaturated monomers water-soluble and water-insoluble respectively, and the thiol compound. CONSTITUTION:A dropping polymerization is carried out by incorporating ( I ) 0.5-20pts.wt. of a reaction product prepared by the reaction in water, in the presence of radical initiating catalyst, between (A) 1-50pts.wt. of a water- soluble ethtlenic unsaturated monomer. (B) 55-99pts.wt. of a water-insoluble ethylenic unsaturated monomer and (C) 0.2-20pts.wt of an organic thiol compound of formula R-(SH)n (R is 2-36C hydrocarbon or organic carboxylic acid residue; n is 1-8) in (II) an emulsion prepared from a mixture of (D) 100pts.wt. of an ethylenic unsaturated monomer (mixture) consisting of (i) 50-100wt% of a C4-12 alkyl(meth)acrylate and (ii) 0-50wt% of another ethylenic unsaturated monomer and (E) 0.005-1pt.wt. of the component (C) to obtain the objecitve dispersion containing the resultant polymer of a Tg -60--10 deg.C.
