Abstract: A thermoplastic adhesive film includes a polyester layer having a moisture permeability of not greater than 5000 g/m2·24 h, and a hot melt adhesive layer disposed on the polyester layer and including a regenerated copolyester. The thermoplastic adhesive film is free from a urethane group. The regenerated copolyester is formed by subjecting a reactant composition containing a depolymerized component to a polymerization reaction. The depolymerized component is obtained by subjecting a recycled polyester to a depolymerization reaction in the presence of a depolymerizing agent. The depolymerizing agent is selected from the group consisting of a polyol component, a polycarboxylic acid component, and a combination thereof. The regenerated copolyester has a melting point ranging from 80° C. to 130° C., a glass transition temperature (Tg) ranging from ?60° C. to 10° C., and an enthalpy ranging from 5 J/g to 30 J/g.

Abstract: The present invention provides a biocompatible and biodegradable elastomer, comprising a hard segment and a soft segment. The hard segment is formed by reacting diisocyanate and a chain extender; and the soft segment is comprising a biodegradable oligomer diol, wherein the biodegradable oligomer diol is selected from the group consisting of polycaprolactone diol, polyethylene butylene adipate diol (PEBA diol), poly-L-lactic acid diol (PLLA diol), polylactic acid diol and any combination thereof. The biocompatible and biodegradable elastomer of present invention can be used to produce vascular graft, cell carrier, drug carrier or gene carrier.
