摘　　要：用聚乙烯醇和甲醛为原料合成了甲醛稳定剂聚乙烯醇缩甲醛 ,用制得的甲醛稳定剂和其它甲醛稳定剂对低醇高浓度甲醛的阻聚效果进行了考察 ,结果表明 ,聚乙烯醇缩甲醛稳定剂在较低温度下对甲醛溶液有较好的阻聚作用。Polyvinyl formal stabilizer for concentrated aqueous formaldehyde solutions was synthesized from polyvinyl alcohol and formaldehyde. The properties of stabilizers were tested, experimental results showed that the polyvinyl formal stabilizer has good inhibition even at low temperature.
