POLYAMIDE TRIBLOCK COPOLYMER WITH AMINO ACID UNITS POLYAMIDE THERMOPLASTIC ELASTOMERS USING THE SAME AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a polyamide-based triblock copolymer having an amino acid unit, a polyamide-based thermoplastic elastomer using the same, and a process for producing the same. The present invention provides a polyamide-based triblock copolymer having amino acid units at both ends of a polyamide oligomer having a controlled molecular weight, wherein the polyamide-based triblock copolymer is a hard segment and the polyether unit is a soft segment (T _m ) of the hard segment is higher than that of the conventional thermoplastic elastomer, the phase separation between the hard segment and the soft segment is facilitated during copolymerization, the mechanical strength is improved, and the biodegradability Is an environmentally friendly elastic body having an amino acid unit and can be applied to all kinds of industries such as household goods, parts of automobiles and electrical and electronic products, medical supplies, sporting goods, and construction and civil engineering products.
