Abstract

Se describe una composicion termoplástica de moldeado que tiene propiedades de liberacion mejorados. La composicion contiene una resina de policarbonato y un agente de liberacion del molde que es un éster que se conforma estructuralmente a R--[-O-CO-R'-O-CO-R"]m donde R es un miembro seleccionado entre el grupo consistente en radicales glicerilo, trimetilolpropilo y pentaeritritilo; m es 2 a 4, R' es un radical hidrocarbonado C8-20 que tiene un grupo alquilo pendiente y R" es el resido de esterificacion de un ácido carboxilico alifático C1-24 o aromático.
