Degradable polymers. III. Synthesis and characterization of aliphatic thermoplastic block copolyesters

Abstract

Block copolymers of dimethyl succinate, ethylene glycol, and polytetramethylene glycol were used to prepare degradable fibres which were then tested for their mechanical properties. Block copolymer samples were also compression-moulded. When the polyether content was increased, a decrease in crystallinity, melting point and fibre strength occurred, whilst the breaking strength increased.
