070021: Poly (1,4-benzodioxepin-3-alkyl-2,5-dione)s: Degradable Polymers with High Glass Transition Temperatures

Polylactic acid (PLA) is growing rapidly in popularity as an alternative to petroleum-derived plastics. It is biodegradable, thermoplastic, and derived from renewable resources. However, polylactides must be crystalline tor them to be dimensionally stable above 50° C, which is a characteristic that limits its use for some applications. Manipulating...

050110: Biodegradable Plastics with High Glass Transition Temperatures Replace PET and Polystyrene

Beginning around 1995, the inventor took an interest in finding ways to make polymers from natural resources since it was apparent that petroleum-based polymers would eventually increase markedly in cost as the world reserves of petroleum diminished. An associate suggested they research making polymers from hydroxyl acids. This led to the idea of...

000020: Process for the Preparation of Polymers of Dimeric Cyclic Esters

Polylactic acid (PLA) is growing rapidly in popularity as an alternative to petroleum-derived plastics. It is biodegradable, thermoplastic, and derived from renewable resources. Presently, the preparation of crystalline materials requires enantiopure L-lactide, where lactic acid is produced by microbial fermentation, and the cyclic lactide monomer...
