Abstract

1.- Oligómero o polímero cristalino o semicristalino que cuando se somete a calor se funde y fluye a una temperatura de entre 60°C y 180°C y cuando se somete posteriormente a curado en el estado fundido mediante radiación y/o energía térmica, dará un recubrimiento que tiene o bien una matriz poilmérica con baja temperatura de transición vítrea (Tg) completamente amorfa sumamente flexible o bien una matriz polimérica con baja Tg de bajo grado de cristalinidad, sumamente flexible. 2.- Oligómero o polímero cristalino o semicristalino adecuado para una composición de recubrimiento en polvo, oligómero o polímero que al curarse mediante radiación y/o energía térmica se convierte en una matriz de polímero flexible que no tiene cristalinidad o tiene cristalinidad reducida. 3.- Oligómero o polímero cristalino o semicristalino adecuado para una composición de recubrimiento en polvo, en el que el oligómero o polímero comprende moléculas de cadena ramificada que contienen a lo largo de la cadena del oligómero o polímero grupos funcionales colgantes distribuidos aleatoriamente siendo de tal forma que proporcionan, al curarse el oligómero o polímero, entrecruzamiento y/o polimerización adicional del oligómero o polímero para dar una matriz de polímero flexible que no tiene cristalinidad o tiene cristalinidad reducida. 4.- Oligómero o polímero cristalino o semicristalino según la reivindicación 1, 2 ó 3, caracterizado porque la flexibilidad de la matriz de polímero obtenida es al menos del 10%, en el que la flexibilidad se determina como el alargamiento a la tracción hasta rotura. 5.- Oligómero o polímero cristalino o semicristalino según una cualquiera de las reivindicaciones 1-4, caracterizado porque al curarse se convierte en una matriz de polímero termoestable que no tiene cristalinidad o tiene cristalinidad reducida. 6.- Oligómero o polímero cristalino o semicristalino según la reivindicación 1, caracterizado porque su temperatura de fusión es inferior a 120°C. 7.- Oligómero o polímero cristalino o semicristalino según la reivindicación 1, 2 ó 3, caracterizado porque la matriz polimérica con baja temperatura de transición vítrea (Tg) completamente amorfa o matriz polimérica con baja Tg, bajo grado de cristalinidad tiene una temperatura de transición vítrea de 30°C o inferior.
