Abstract

PURPOSE: To reduce the unreacted monomers in an acrylic polymer by carrying out the polymerization in two stages wherein the first stage polymerization is conducted in the presence of an inorganic redox catalyst, and the subsequent second stag polymerization in the present of a specific additive.
CONSTITUTION: In the aqueous polymerization of acrylic monomers (A) the first stage polymerization is carried out in the presence of an inorganic redox catalyst. Subsequently (B) the second stage polymerization is carried out in the presence of an organic peroxide, an aldehyde and the other reducing agent ( preferably sodium ascorbate, etc.).
EFFECT: Free from discoloration with time and yellowing by thermal treatment.
