Abstract

Procedimiento para la preparación de resinas de silicona endurecibles por calor, mediante reacción de alcoxisiloxanos con compuestos hidroxílicos orgánicos polifuncionales, caracterizado porque se hacen reaccionar entre sí siloxanos de la fórmula general **(Fórmula)** en donde OR1 significa un grupo alcoxi de alcoholes alifáticos primarios o secundarios con 1 a 4 átomos de carbono, R2 es un grupo alcohilo y/o fenilo, a tiene un valor de 1,0 a 1,5, b tiene un valor de 0,1 a 0,7, con alcoholes polivalentes de bajo peso molecular a temperaturas de 100 a 160ºC, eventualmente en presencia de catalizadores de transesterificación y disolventes en sí conocidos con eliminación del alcohol R1OH en una proporción cuantitativa tal que a un grupo SiOR1 corresponde aproximadamente un grupo COH y se interrumpe la reacción con un grado de conversión de 25 a 80% mediante enfriamiento a una temperatura menor de (<) 100ºC.
