摘要：

This paper deals with synthesis and characterization of a novel poly(N-propargylamide) containing cinnarnamide groups (poly(1)) in its side chains. Monomer 1, CH equivalent to CCH2NHCOCH=CH(C6H5), was synthesized and polymerized with a rhodium catalyst, (nbd)Rh+B-(C6H5)(4) (nbd = 2,5-norbornadiene). Effects of some factors on polymerization of monomer 1 such as solvent, detail; polymers with moderate number-average molecular weights ((M) over bar (n)) and low index of polydispersity ((M) over bar (W)/(M) over bar (n)) were obtained. To improve the polymers' solubility and to elucidate whether poly(1) could form helical conformation, another N-propargylamide monomer 2, CH equivalent to CCH2NHCOCH(CH2CH3)(2), was employed to accomplish copolymerization with monomer 1. Copolymerization with monomer 2 improved obviously the solubility of the (co)polymers; the copolymers with certain monomer ratios could form helices under the examined conditions according to the related UV-vis spectra.
