Claims
- 1. A process for producing an aqueous copolymer dispersion, wherein the polymer has a glass transition point ranging from -10.degree. C. to -90.degree. C., which consists of:
- emulsion polymerizing, in an aqueous medium containing a polymerization initiator, 100 parts by weight of a vinyl monomer mixture consisting of (A) from 60% to 99.8% by weight of 2-ethylhexyl acrylate, (B) from 0.2 to 10% by weight of an .alpha.,.beta.-unsaturated carboxylic acid, and (C) up to 30% by weight of a vinyl monomer other than monomers (A) and (B) in the presence of an emulsifying agent and from 0.01 to 10 parts by weight of a compound having an allyl hydrogen atom selected from the group consisting of abietic acid and derivatives thereof having the formula: ##STR4## wherein R is hydrogen or alkyl and the encircled H groups represent allyl hydrogen atoms, and allyl alcohol.
- 2. The process as claimed in claim 1, wherein said compound having an allyl hydrogen atom is present in an amount ranging from 0.1 to 3 parts by weight per 100 parts by weight of the total monomers.
- 3. The process as claimed in claim 1, wherein said component (B) is present in an amount ranging from 0.5 to 5% by weight based on the total monomer content.
