摘要
研究了尼龙 - 6 6在甲酸中与甲醛反应 ,于 6 0℃生成 N-羟甲基化尼龙 - 6 6 ,同时又研究了尼龙 - 6 6与甲醛的甲醇溶液反应生成 N-甲氧甲基化尼龙 - 6 6 ,结果使尼龙 - 6 6的熔点分别降为 180～ 190℃和 15 0℃ ,同时降低了模数 ,改善了其在乙醇中的溶解性 ,提高了粘结性 。
In order to decrease nylon 66′s melting point and improve its adhesivnity, it has been studied that nylon 66 reacted with formaldehyde in the presence of formic acid at the temperature of 60 ℃ to yield an N methylol derivative or with the solution of formaldehyde in methanol to yield an N methoxymethyl 66, with its melting point decreased to 180~190 ℃ and 150 ℃ respectively, its modulus decreased too, its solubility in ethanal improved and at the same, its adhesivity increased. As a result, the product can be used as coating and adhesion.
