摘要
合成了一种丙烯酸酯共聚物，用ＧＰＣ法测得的Ｍｎ＝１．１０×１０＾４，ＭＷ＝２．７１×１０＾４，分散性２．５。用ＤＳＣ法测得Ｔｇ＝３４．０８℃。在共聚物中加入中和剂和水配制成半透明无皂水溶胶，胶粒直径７５ｎｍ，稠度系数Ｋ＝１．８４５，表面张力２８．５ｄｙｎ／ｃｍ。在水溶胶中加入固化剂和催化剂，配制无皂水性涂料。涂料具有良好的冻融稳定性、贮存稳定性、耐水性和耐酸碱性等。
An acrylate copolymer has been prepared,whichhas the Mn 1.10×10~4,Mw 2.71×10~4.MWD2.5 by GPC,and Tg34.08℃ by DSC.A semi-transparent soap-free aquosol can be formed byaddition in the copolymer the neutralizer andwater with the sol particle diameter 75nm.con-sistency coefficient K1.845 and surface tension28.5 dyn/cm.A soap-free water-borne coatingcould be formulated by further addition of hard-ener and catalyst in aquosol,which has betterfreeze-thaw stability.storage stability.water resistance and acid and alkali resistance.
