NEW BIODEGRADABLE POLYMERS DERIVED FROM [ N,N']-DIACYL-BISPHENYLALANINE

New polyamides and poly(amide-esters) derived from [N,N']-terephthaloy l-bis-L-phenylalanine and [N,N']-adipoyl-bis-L-phenylalanine were synt hesized using active polycondensation technique. The bis nucleophiles used in the synthesis were hexamethylenediamine, methyl [N,N]-bistrime thylsilyl-L-lysinate, and bis-L-phenylalanylbutane-1,4-diol di-p-tolue nesulfonate. Some physicochemical properties and alpha-chymotrypsinoly sis of the polymers prepared were studied. Factors affecting alpha-chy motrypsinolysis of the polymer substrates were discussed.
