Abstract
Un tubo acrílico de luz, como se describe en las patentes de E. U. A., de Bigley y colaboradores, Nos. 5,406,641 y 5,485,541, tiene una estabilidad térmica adecuada para muchos propositos. Se ha encontrado que se puede impartir una estabilidad térmica mejorada, segun se refleja en la formacion de color, ajustando las condiciones de polimerizacion, para producir el polímero de nucleo sin curar de la construccion de nucleo/revestimiento con un contenido de vinilo terminal muy reducido.
