内容記述 | In a previous paper,the authors defined a network polymer composed of different polymeric chains as "heterogeneous network polymer", and reported the synthesis and a few mechanical properties of [PCbzLL]-[PEG-HMDI]type heterogeneous network polymers. In this paper, the heterogeneous network polymers were prepared by crosslinking polylysine chains with hydrocarbon chains through urethane bridges. The following procedures were adopted. [Procedure 1] Interfacial condensation method PLL-HC1 were allowed to react with butanebischloroformate. [Procedure 2] NCA (N-Carboxy anhydride) method Bis-ε-N -carboethyleneoxy-L-lysine was prepared by reacting L-lysine HC1 with butanebischloroformate and then converted to bis-ε-N-carboethyleneoxy-L-lysine N-carboxy anhydride by phosgenation. The network polymers were obtained by the polymerization of bis-NCA. The structures of these network polymers could be varied by changing the molar ratio of amino group of [PLL・HCI] to chloroformate in procedure 1,and by changing the molar ratio of bis-NCA to mono-NCA in procedure 2. The heterogeneous network polymers thus obtained were pale-yellow,stiff or curdy particles from procedure 1, and leathery or resinous fi1m from procedure 2. The polymers swelled in dimethylacetamide, dimethylformamide, dichloroacetic acid, formic acid etc. A typical polymer prepared by procedure 2 showed Tg at -2℃ and high modulus above room temperature. | |||||
