摘要
聚酷酸乙烯(PVAC)乳液生产过程中普遍存在有“挂放”问题,在酷酸乙烯(VAC)进行乳液聚合初期加入微量甲醇,可有效地防止这种现象,并且还起消泡剂和助乳化剂作用,有利于提高产品质量。
Suspensoid presents widely in the production of PVAC emulsion. This can be reduced by adding trace methaol at the initial period of VAC emulsion polymerization . Methanol acts also as antifoaming agent and emulsifier auxiliary
