Abstract:
1. An organic resin matrix composition comprising: (a) a curable reaction product of: (a1) an organic resin featuring hydrogen active groups and (a2) a compound containing a thermolabile carbonate group, wherein the thermolabile carbonate group is grafted onto the backbone of the organic resin by reaction of said compound with said hydrogen active groups; (b) a curing agent; (c) an optional solvent; and (d) an optional catalyst; wherein heating of the organic resin matrix composition to a temperature of about 120° C. to about 220° C. results in thermal degradation and volatilization of the thermolabile group such that nano size voids are produced in the resulting cured organic resin matrix.
