| Summary: | 碩士 === 國立臺北科技大學 === 化學工程所 === 94 === In this study, hyperbranched polymers were prepared by diepoxides(A2), multi-function amine monomers (Bƒ), and monoepoxide (AR) in a solvent. First, the dependence of the structure parameters, such as molecular weight, and polydispersity, of the hyperbranched polymers on the ratio of A2/ Bƒ /AR and concentration were discussed. By adding the monoepoxides, the number average molecular weight of the polymers of 7343 ~ 2333 with PDI of 2.6 ~ 4.4 can be obtained. Furthermore, the feed rate of the Bƒ monomers added into the mixture of the A2 and AR can also result in different molecular weight distribution of the hyperbranched polymers. It is worthy to be further studied.
