Enzymatically catalyzed polycondensation of p - xylylenediamine and diethyl sebacate resulted in oligo ( p - xylylene sebacamide ) with high melting temperatures ( 223 - 230 degrees C ) and the enzymatic polycondensation of dimethyl terephthalate and 1 , 8 - diaminooctane leads to oligo ( octamethylene terephthalamide ) with two melting temperatures at 186 and 218 degrees C .
 Chemical: p - xylylenediamine; Chemical: diethyl sebacate; Chemical: oligo ( p - xylylene sebacamide ); Chemical: dimethyl terephthalate; Chemical: 1 , 8 - diaminooctane; Chemical: oligo ( octamethylene terephthalamide )
