摘　　要：提出了用淀粉醋酸酯与醋酸乙烯接枝共聚制备白乳胶的新工艺。结果表明制得的白乳胶与单独用PVA作为保护胶体制得的白乳胶相比,粘度和耐水性得到改善,粘接强度均能达到使用标准。作为一种新型胶粘剂,其与环境相容性好,前景广阔。A new technology of grafting copolymerization of vinyl acetate onto starch acetate is put forward to prepare white glue. The results show that viscosity and waterproof property of the product are improved compared with that of white glue using PVA alone as protective colloid. And its adhesive strength can achieve the standard of using. As a new environmental friendly adhesive,this kind of white glue has a good future.
