How to determine the length between cross-links from DMA rubbery modulus in photopolymer resin consisted from 2 monomers?

12 December 2017 0 8K Report

I have a DMA measurement of copolymer resin composed from two bifunctional methacrylate monomers with significantly different molecular lengths (one is relativelly short and second is long). I need to extract average length between chemical cross-links of this network and consequently network density.
