Biothermoplastic elastomer (BTPE), influence of architecture on mechanical properties

Biodegradable thermoplastic elastomer was acquired by synthesizing four-armed and three-armed star-shaped copolymers via ring-opening polymerization with multifunctional initiator, such as pentaerythritol and glycerol, using stannous octoate (SnOct2) catalyst in bulk at 130oC. Random copolymer of PC...
