研究了无皂改性醋酸乙烯酯乳液的合成工艺及条件,并采用小角激光散射仪,测得了粒子的粒径大小及分布;探讨了单体浓度、引发剂浓度、缓冲剂浓度等对粒径的大小、分布的影响及规律;用扫描电子显微镜,对粒子的形态进行了观测。用红外光谱仪,对聚合物的结构进行了表征。 The synthesis process and conditions of soap-free modified vinyl acetate emulsion were studied. The particle size and distribution of the particles were measured by a small-angle laser light scattering instrument. The effects of monomer concentration, initiator concentration and buffer concentration on the particle size The size of the distribution and the influence of the law; with the scanning electron microscope, the particle morphology was observed. The structure of the polymer was characterized by infrared spectroscopy.
