Abstract

PURPOSE:To improve each resisting property of heat, solvent and hydrolysis and especially water permeability, by making semipermeable membraneous substance on both sides of diene compound polymer from block polymer composed of amino acid compound polymer. CONSTITUTION:Intermidiate component composed of polymer of diene compound monomer, such as polybutadiene, as one component at least having 0.5-50% of volume partial ratio of constituent being mean molecular weight 500-30000, is made. Both sides block component is made on both sides of the above component by amino compound polymer being single polymer of amino acid, such as alanine etc. and its derivatives, copolymer. In order to obtian such polymer, for example, N-carboxy-alpha-amino acid anhydride, is polymerized on both sides of the above intermediate component given amino radical at both ends. About 100-2000 times of water permeating property compared with that of membraneous substance composed of amino acid polymer being not block copolymer, is shown by this semipermeable membraneous substance.
