Document Type and Number:
Japanese Patent JP3292551
Kind Code:
B2
Abstract:

PURPOSE: To improve the stability of emulsion during emulsion polymn. and obtain a polymer emulsion which provides a polymer and a film having remarkably improved water resistance, heat resistance, and adhesive properties by using a specific reactive emulsifier.
CONSTITUTION: A reactive emulsifier for emulsion polymn. is represented by formula I [wherein R1 is 6-30C alkyl; R2 is H or methyl; A is a 2-4C optionally substd. alkylene group; n is an integer of 1-200 provided when n is 2 or higher, then (AO)n may be a homopolymer comprising one kind of repeating unit as shown by formula II or may be a block- or random-copolymer comprising two or more kinds of repeating units having different A's (A1, A2,...0 as shown by formula III (wherein n1+n2+...=n); m is 1 or 2; and M is H, an alkali metal, an ammonium ion, or an alkanolamine residue].
