摘要: Epoxy polymers composed of bisphenol A (BPA) and epichlorohydrin (ECH) were grafted onto polyurethane (PU) using the graft-polymerization method to prepare epoxy PU hybrid polymer. The main series contained polymer PU; however, was not bound in control series. breaking tensile stress steeply increased at low BPA ECH contents then decreased as more included series, whereas did display an incline irrespective contents. percent shape recovery also after grafting but a slower rate flexibility freezing temperature enhanced compared with plain because effectively disrupt molecular interaction between PUs. Therefore, noticeably strength PU.
