WebJul 15, 1996 · Conformational Analysis of Methyl−Phenyl−Siloxane Chains. The conformational energy of chain fragments of poly (methylphenylsiloxane) is studied, considering contributions from bond stretching, bond angle bending, bond torsion, and van der Waals interactions. Energy is minimized without constraints, so that minima … WebMay 1, 2003 · The phenyl group in the chain is bulky and disturbs the crystallization [7], [9]. Silicone elastomers are made by crosslinking functionalized polydimethylsiloxane. Two major curing mechanisms are frequently used, free radical and addition. These two processes transfer the polymer from the liquid state into the elastomer state.
