摘要：
2-component polymer systems are prepared from hydrophilized unsaturated polyester (HUP) resins and urea-formaldehyde (UF) resins. There are temperature transitions in dynamic-mechanical functions which represent viscoelastic properties of these polymer systems and corresponding relaxations between the glassy and the elastic states. These high molecular weight systems are polymer blends in the wt-ratio 90/10 of the starting system and interpentetrating networks at 70/30 or 40/60.
