They can also be used for fiber sizing , textile finishing , the reinforcing agent for cement and ceramics , and the preparation of various kinds of latex paints , and all kinds of special adhesion agents . the products of vinyl acetate - acrylic ester copolymer emulsion , which have overcome some defect of homopolymerized products , are newly developed . the modified emulsion has stronger water resistance , better flexibility , and lower glass state temperature 醋-丙共聚系列乳液产品是针对均聚产品的某些缺陷而发展起来的新胶种，它通过醋酸乙烯与丙烯酸脂类共聚改性，提高胶粘剂的耐水性和柔韧性，降低共聚物的玻璃化温度，使产品对一些均聚乳液难以粘接的材料具有良好的粘接性能，主要产品有：宝丽板胶铝箔纸胶塑板胶等。
Polar polymers tend to separated from upr and make system form co - continuous structure , which make for shrinkage compensation . big difference of glass transition temperature ( tg ) between upr and lpa and a tg below the cure temperature is preferred , because there is more time and more efficient for microvoid formation of cured sample 极性较大的lpa在固化过程中更有利于从upr相中分离出来，形成有利于补偿收缩的两相交互连续的形态结构，而玻璃化温度与upr的差别大且低于固化温度的lpa ，则使得固化试样形成微孔的时间长和效率高。
