Reactions that form these can use iniferters with dithiocarbamate groups to catalyze and ends the reaction.

O-rings are made of a type of these materials that have a low Young's modulus and high failure strain above their glass transition temperature. One theory of them considers their layout on a lattice and calculates the entropy and change in Gibbs free energy of mixing them with a solvent; that theory is due to (*) Flory and Huggins. A model of them that assumes all bond lengths are the same and bond angles are random is the freely jointed chain model, and when all of their substituents are on the same side, they are called isotactic. For 10 points, name these large molecules made up of chains or networks of smaller molecules.
