EP/PVB半-互穿聚合物网络的动态力学谱

Dynamic mechanical spectra of semi-interpenetrating networks based on epoxy resin and poly(vinyl butyral)

制备了EP/PVB半 互穿聚合物网络 .动态力学谱结果表明 ,适量的PVB对环氧树脂有较好的增韧作用 ,而环氧树脂对PVB的增硬作用不明显 .

Semi IPNs based on epoxy resin and poly(vinyl butyral) were prepared. The results of dynamic mechanical spectra showed that epoxy resin can be obviously toughened by the opportune amount of PVB but poly(vinyl butyral) can be weakly hardened by epoxy resin.
