Abstract
The crosslinking reactions that occur in unsaturated polyester resins result in a heterogeneous structure of highly crosslinked domains sepa rated by less highly crosslinked material. This structure is a result of the formation of gel particles, which are initiated at free radical s during the curing reaction. Controlling the concentration of free ra dicals present in the system enables the heterogeneity within the resi n to be varied, and its influence on the thermomechanical properties t o be studied.
