Two copolymers(S-1, S-2) were prepared from styrene with N-vinylpyrrolidone and N, N-diethylacrylamide respectively. The partly neutralized acrylate (sodium) was polymerized in cyclohexane by using the copolymers as an inverse suspending agent. When S-1 meeted 8%< F_2W< 20% and 1.2 ×10⁴< M< 7.5 ×10⁴ the polyacrylate obtained had a particle size of 0.3~2.6mm and a high water absorption ability. Using S-2 as suspending agent the particle size of polyacrylate was ca.1 mm. The copolymers have the advantages of improving the particle size of polyarylate and a little adhesion to reactor.
