title: [Synthesis and characterization of biodegradable alpha,beta-poly (3-hydroxypropyl, propyl)-DL-asparamide].
abstract: A biodegradable condensation polymer alpha,beta-poly (3-hydroxypropyl, propyl)-DL-asparamide has been synthesized. Its monomer is DL-aspartic-acid and its spacers are mixture of 3-amino-propanol-1 and propylamine. The polymers thus synthesized are characterized by 1H-NMR, water sorption and intrinsic viscosity. For the purpose of applicability, we have synthesized the polymers with different properties in reference to the molar ratios of propyl amine to 3-amino-hydroxypropyl in polymer synthesis.
