For the PUU/BO-g-VER (n-butanol graft VER network)hybrid film, the miscibility between the soft and hard segments in PUU phase was improved byadding the BO-g-VER network into PUU, resulting in remarkable reinforcement effect andgreat improvements of mechanical properties for the films. In the PUU/200-g-VER [Mn: 200,poly graft VER], the 200-g-VER network had considerable compatibility withboth hard segments and soft segments in PUU phase, then good reinforcement effect wasrealized, giving rise to higher tensile strength and elastic module, lower elongation at break ofthe hybrid films.

由于BO-g-VER与PUU硬段具有较好的相容性且促进了PUU软硬段间的微相混合，导致PUU／BO-g-VER hybrid膜的力学性能有较大程度的提高，体现了明显的增强效果。200-g-VER(分子量为200的单官能团聚醚接枝VER)与PUU软硬段均有很好的相容性，因此PUU／200-g-VER hybrid有较好的增强效果，使胶膜的拉伸强度和弹性模量提高，断裂伸长率下降。
