COPOLYAMIDE COMPOSITIONS DERIVED FROM TRIGLYCERIDES

摘要

Disclosed is a copolyamide including at least two repeat units selected from the group consisting of structures (I) to (IV),—C(O)(CH2)10C(O)NH(CH2)nNH—  (I);—C(O)(CH2)12C(O)NH(CH2)nNH—  (II);—C(O)(CH2)14C(O)NH(CH2)nNH—  (II); and—C(O)(CH2)16C(O)NH(CH2)nNH—  (IV); and n is an integer selected from 4, 6, 10 or 12; wherein at least one repeat unit is selected from structures (I) and (II); and any one the repeat units may be present up to about 92 mole percent. Also disclosed is a process for providing the copolyamide; and thermoplastic compositions and tubing including the copolyamides.
