✦ Synopsis

The dynamic mechanical T 0 of styrene-poly(diethylene succinate fumarate) networks has been quantitatively related to the crosslink density. The crosslinking constants, derived from this analysis, were compared with those obtained from other network systems. It is concluded that the crosslinking constant of Di Marzio is not a universal constant; however, a related parameter was found to be very nearly material independent.

## Abstract Unsaturated polyesters have been synthesised and modified to determine the effect of number‐average molecular weight (MΜ„~n~) and molecular weight distribution (MWD) on the following properties of the polyesters after crosslinking with styrene: (i) water absorption, (ii) initial mechanic
