Copolímeros de Injerto con Respuesta a la Temperatura y Ph by Emilio Bucio and Héctor Iván Meléndez Ortiz (2013, Trade Paperback)

En este trabajo dos nuevos copolimeros de injerto binario fueron sintetizados empleando radiacion gamma proveniente de una fuente de cobalto sesenta. Para la sintesis de dichos copolimeros, primeramente se llevo acabo el injerto de N, N'- dimetilaminoetilmetacrilato (DMAEMA)y 4-vinilpiridina(4VP)en polipropileno (PP) por el metodo de irradiacion directa. Posteriormente, se injerto N-isopropilacrilamida NIPAAm) en PP-g-DMAEMA y PP-g-4VP por el metodo de preirradiacion oxidativa. La dependencia de la dosis de irradiacion, temperatura, tiempo de reaccion y concentracion de monomero sobre los porcentajes de injerto de NIPAAm fue estudiada. Los copolimeros de injerto fueron caracterizados mediante espectroscopia de infrarrojo(FTIR-ATR), analisis termogravimetrico (TGA) y calorimetria diferencial de barrido (DSC)."
