摘要: 水溶液中丙烯酸/乙酸乙烯酯无规共聚物的存在不仅降低了Na2SO4和CaCl2生成CaSO4的沉淀量和结晶速度,而且可显着减小CaSO4粒子的大小,改变其形状和晶形,降低结晶的完善程度.

Abstract: Presence of title copolymer in the aqueous solution of Na2SO4 and CaCl2 not only decreases the amount and crystallization rate of CaSO4 precipitate, but also markedly reduces its particle size and changes its morphology and crystal form.

Key words: acrylic acid/vinyl acetate copolymer, calcium sulfate, precipitate, crystallization, morphology
