專利摘要：
An organic polyurethane shape memory material includes a C10 chain or C18 chain and consists of hard segment and soft segment. The material is produced by reacting the single-chain type dendrimer with diethylenetriamine to produce dendrimer. Then dendrimer reacts with N-(3-aminopropyl)diethanolamine to produce dendritic diols. Next, polymer HO(C 6H10O2)xC2H4OC2H4(C6H10O2)yOH, where x+y=25˜26, reacts with methylenedi-p-phenyl diisocyanate, and at least one type of dendritic diols is added to produce the organic polyurethane shape memory material.
