Solid elastic reinforced sparsely cross-linked polymers in rubberlike state have been studied. These materials are alternatives to fibrillar “dry” adhesives. The polymers based on sparsely cross-linked elastic polyester urethanes allow one to vary the composition of material, molecular and supramolecular structures, phase morphology, and strain–strength characteristics with a clear “dry” adhesion effect in a broad range. It has been stated that theoretical models developed for the calculation and prediction of adhesion characteristics of such materials should consider a clear viscoelasticity of elastic sparsely cross-linked polymers and should be based on contemporary approaches of failure mechanics, in particular, models of cohesion zones.

具有不成形表面的弹性增强“干”粘合剂材料

已经研究了橡胶状状态的固体弹性增强稀疏交联聚合物。这些材料是纤维状“干”粘合剂的替代品。基于稀疏交联的弹性聚酯氨基甲酸酯的聚合物允许人们改变材料的组成、分子和超分子结构、相形态和应变强度特性，并在广泛的范围内具有明显的“干”粘合效果。已经指出，为计算和预测此类材料的粘附特性而开发的理论模型应考虑弹性稀疏交联聚合物的明确粘弹性，并应基于现代失效力学方法，特别是内聚区模型。
