Title: | Semi-crystalline shape memory polymer and production method thereof | Authors: | Hu, J Zhu, Y Han, J Lu, J |
Issue Date: | 27-Dec-2016 | Source: | US Patent 9,527,947 B2. Washington, DC: US Patent and Trademark Office, 2016. | Abstract: | A semi-crystalline shape memory polymer with transition temperature near body temperature and the production method thereof is disclosed. The shape memory polymer comprises a polymer chain which further comprises a plurality of prepolymers and a plurality of chain extenders bonding the prepolymers together in which each prepolymer further comprises a plurality of synthesized units. The above mentioned synthesized unit is obtained by reacting polymer diol with first diisocyanate. The obtained synthesized units are polymerized together with second diisocyanate and chain extender to form the shape memory polymer. | Rights: | Assignee: The Hong Kong Polytechnic University |
