Abstract

UN METODO PARA SINTETIZAR UN COPOLIMERO DE UN PRIMER ALFA-AMINOACIDO CARBOXILICO Y UN SEGUNDO ALFA-AMINOACIDO CARBOXILICO QUE COMPRENDE LOS PASOS DE: FORMAR UNA MEZCLA DE DICHOS PRIMER Y SEGUNDOALFA-AMINOACIDOS CARBOXILICOS, SIENDO EN DICHA MEZCLA LA RELACION MOLAR DEL PRIMER ALFA- AMINOACIDO CARBOXILICO AL SEGUNDO ALFA-AMINOACIDO CARBOXILICOO DE 40/60 A 60/40; REACCIONAR DICHA MEZCLA CON FOSGENO PARA FORMAR UNA MEZCLA RESULTANTE DE UN N-CARBOXIANHIDRIDO DEL PRIMER ALFA-AMINOACIDO CARBOXILICO Y UN N-CARBOXIANHIDRIDO DEL SEGUNDO ALFA-AMINOACIDO CARBOXILICO; REDUCIR EL CONTENIDO DE ION CLORURO DE DICHA MEZCLA RESULTANTE A MENOS DE 0, 1%, Y POLIMERIZAR LA MEZCLA RESULTANTE TRATADA PARA FORMAR DICHO COPOLIMERO DE DICHOS PRIMER Y SEGUNDO ALFA-AMINOACIDOS CARBOXILICOS.A METHOD FOR SYNTHESIZING A COPOLYMER OF A FIRST ALPHA-CARBOXYLIC ALPHA-AMINO ACID AND A SECOND ALPHA-CARBOXYLIC AMINO ACID WHICH INCLUDES THE STEPS OF: FORMING A MIXTURE OF THESE FIRST AND SECOND ALFA-ALFA-ELINOA-DELICA-LABOR IN DIAZAR, ALLAH-DELA-ALLAH-LAUNCHA CARBOXILICO TO THE SECOND ALPHA-AMINOACIDO CARBOXILICOO FROM 40/60 TO 60/40; REACT SUCH MIXTURE WITH PHOSGEN TO FORM A RESULTING MIXTURE OF A N-CARBOXYXYHYDRIDE FROM THE FIRST ALPHA-AMINO ACID CARBOXYLIDE AND A N-CARBOXYHYDRIDE OF THE SECOND ALPHA-CARBOXYL AMINO ACID; REDUCE THE CONTENT OF CHLORIDE ION IN SUCH RESULTING MIXTURE TO LESS THAN 0, 1%, AND POLYMERIZE THE RESULTING MIXTURE TREATED TO FORM SUCH FIRST AND SECOND COPOLYMER OF SUCH FIRST AND SECOND ALPHA-CARBOXYL AMINO ACIDS.
