Abstract
PURPOSE: To prepare the title suspension capable of giving an aqueous coating material having improved coating performance, with excellent color and storage stability for a long time, by using a salt of an oligostyrene-sulfonic acid derivative as a dispersing agent.
CONSTITUTION: A preliminarily formed polymer cake is finely dispersed in water with a salt of an oligostyrenesulfonic acid derivative of formula I: (R is H or 1W 10C alkyl group; M is Na+, K+, Li+, Cs+, NH4 +, Ca2+, Mg2+ or Zn2+; n is an integer 5W1,000; m is an integer 1W1,000 but not larger than n), as a dispersing agent by a colloid mill to give an aqueous suspension of formaldehyde polymer of good quality. The acid derivative may by a copolymer having two or more different R groups in one molecule.
