Abstract

POLIMEROS BIODEGRADABLES DE ESQUELETO CARBONADO DE ACETALES DE CETENO Y ALCOHOLES, PROCEDIMIENTO PARA SU OBTENCION Y COMPOSICION Y UTILIZACION CORRESPONDIENTES. EL ESQUELETO CARBONADO DE LOS POLIMERAS ESTA REPRESENTADO POR LA FORMULA REPETITIVA I, DONDE N < 2; R2 GRUPO HIDROCARBONADO SATURADO O INSATURADO; Y A UN ACETAL DE CETENO DE (A) FORMULA III FORMULA R H O UN GRUPO SATURADO O INSATURADO SUSCEPTIBLE DE CONTENER HETERATOMOS; R---R SIGNIFICA QUE LOS R PUEDEN FORMAR CICLO O NO; Y R1 RADICAL TETRAVALENTE UNICO; O (B) FORMULA IV FORMULA R4 H O UN GRUPO HIDROCARBONADO; R4--R4 SIGNIFICA QUE R4 PUEDEN FORMAR CICLO O NO; R3 GRUPO ORGANICO BIVALENTE SUSCEPTIBLE DE CONTENER HETEROATOMOS. ESTOS POLIMERAS SON APROPIADOS COMO SOPORTE DE MEDICAMENTOS Y OTROS AGENTES BENEFICIOSOS UTILIZADOS EN EL AMBITO TERAPEUTICO, PUESTO QUE AL ENTRAR EN CONTACTO CON EL MEDIO FISIOLOGICO EN EL QUE SON UTILIZADOS, SE DEGRADAN Y LIBERAN EL MEDICAMENTO O SIMILAR DE UNA FORMA PROGRESIVA Y CONTROLADA.
