At the theta point, the self-repulsion of these substances matches a random walk model.
At the theta point, the self-repulsion of these substances matches a random walk model. They aremodeled by an exponentially-decaying correlation function in the Kratky-Porod model. Substanceslike DEHP and DINP can be used to lower the glass transition temperature of these substances. Ifthey can be dissolved and softened to be remolded into their old shape, they are called (*) thermoset.The formation of covalent bonds within these substances leads to an increase in their strength calledcrosslinking. Carothers' equation gives the namesake degree of the formation of these substances, whichcan proceed via a "step-growth" process. A synthetic example of them is Teflon. For 10 points, name theselong molecules made of monomer units.
