摘要: 三聚氰胺甲醛树脂(MF)为非晶态高聚物,有广泛用途,已有许多改性的MF树脂产品。我们曾认为三聚氰胺甲醛树脂和聚乙烯醇(PVA)复合物中可能有单晶存在。本文对此单晶作进一步的确认。

Abstract: The structure of melamine formaldehyde resin/poly(vinyl alcohol) (MF/PVA) composites has been studied with transmission electron microscopy,electron diffraction and X-ray diffraction techniques. The single crystals found in MF/PVA(90/10) composite are monoclinie with a=0.51nm,b=1.69rim,c=0.53nm and β=59.5°.

Key words: melamine formaldehyde resin, poly (vinyl alcohol), composite, single crystal
