Purely deterministic derivations are reported regarding the internal, network chain structure that contributes to rubber elasticity in polymerizations of A2−A2+B2 monomers. The A2−A2 monomer originally contained two primary sites. Upon reaction,

Subject to intermolecular addition and intramolecular cross-linking reactions, deterministic models which describe chain infrastructure for a random A4 + B2 resin and a Poisson-type, chain-initiated epoxy anhydride thermoset were derived. Sol fractio

A linear-chained epoxy resin was formulated from phenyl glycidyl ether and nadic methyl anhydride catalyzed by benzyldimethylamine. Intermolecular polymerizations were modeled as a parallel set of propagation reactions. Fourier-transform infrared spe
