    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(C6H10O2)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.

    摘要: The present invention relates to a one-pot synthetic method for synthesizing silver-containing waterborne polyurethane (WBPU). The method includes the steps of adding a silver ion-containing solution, such as silver nitrate solution, into WBPU emulsion to form a silver-containing PU emulsion by stirring, and dehydrating the silver-containing PU emulsion so as to obtain a WBPU containing nano-scaled silver particles having a uniform particle size and good dispersibility. The present invention provides a method that can be easily and speedily operated, and the silver-containing WBPU prepared according to the method of the present invention exhibits excellent antibacterial, bactericidal and deodorant effects but using a small amount of silver.

    摘要: A facile synthesis of amphiphilic hyperbranched polymers consisting of poly(amic acid) and polyimide was developed via “A2+B3” approach from difunctional anhydride and trifunctional hydrophilic poly(oxyalkylene)triamine. Various amphiphilic hyperbranched poly(amic acid)s (HBPAAs) with terminal amine functionalities and amic acid structures were prepared through ring-opening polyaddition at room temperature, followed by thermal imidization process for the formation of hyperbranched polyimides (HBPIs), accordingly. The resulting HBPIs were analyzed by GPC, indicating the molecule weights of 5000˜7000 g/mol with a distribution of polydispersity between 2.0 and 3.8. The amine titration for HBPIs indicated the peripheral total-amine contents to be 8.32˜18.32 mequiv/g dependent on compositions.
