Abstract:

The use of glass in solar collectors suffers from several limitations, chief of which is breakage resulting from falling or thrown objects, from temperature changes, and from internal stresses. Substitution of a polymer with much higher impact resistance for glass will overcome these disadvantages. Therefore, it is the purpose of this program to develop polycarbonate polymers and copolymers with glass transition temperatures higher than 150 deg C, good optical, physical, and mechanical properties, and markedly improved resistance to ultraviolet radiation. A second objective is to develop a surface treatment that minimizes reflectance if a sufficiently good polycarbonate can be developed during the course of the program. jg p9
