碩士 === 輔仁大學 === 化學系 === 84 === Many homogeneous elastomeric network are found to obey the semi-empirical Mooney-Rivlin eq,which is an equation relating to strain through the use ofevidence for the relationship between stress-strain isotherm and interpenetratingpolymeric network. In this study,we attempted to synthesize a series of homogeneous polydimethylsiloxaneIPN via free radical and condensation reaction.Incomplete reaction during synthesis of the network due to interference of Tin catalyst and BPO willobviously effect the experimental results dramatically. In the highly swollen state, the real network exhibits properties closer to those of the phantom network,which is the extreme case of infinitive elongationin Mooney-Rivlin eq.By calculation,the experimental results of the two different methods are consistent with each other.
