摘　　要：报道了一种制备聚乙烯醇缩醛胶的新配方。常规的制备方法是通过甲醛和聚乙烯醇的缩合反应来实现的。作者发现，在反应中加入适量乙醛代替部分甲醛、可明显提高缩醛胶的性能。In the presen paper, a new formula for the preparation of polyinyl acetal adhesive has been introduced. The conventional method was by the condensation reaction of formaldehyde and polyvinyl alcohol. The authors find that the addition of appropriate amount of acetaldehyde to replace a part of formaldehyde distinctly improves the properties of the acetal adhesive.
