Abstract
There are provided compositions, systems and methods to fabricate bio-based and biodegradable elastic materials in the form of fibers, foams and molded objects, as well as various articles made using the same. The elastic materials consist primarily of di-acids and di-alcohols with or without crosslinkers and supporting polymer structures.
Claims71
A stretchable polymer made from reacting one or more di-alcohols with a di-acid or tri-acid, followed by curing at high temperatures.
A stretchable polymer made from reacting a di-alcohol with a di-acid in the presence of a crosslinking agent comprising both a thermal initiator and a photoinitiator, followed by extrusion and subsequent curing with ultraviolet light (UV).
A biodegradable, compostable, and bio-based elastomeric fiber which has an elongation ratio of at least 50% and a maximum elongation ratio of 1000%, can recover its original length fully upon removal of stress, and can undergo at least 100 cycles of relaxation and elongation without any fatigue.
