Hydroxy-terminated silarylene-siloxane prepolymers

The third set of silarylene-siloxane-diacetylaie polymers that were reported by Homrighausen et al. also produced elastomeric networks on curing (Figure 15.16) [33]. The precursor polymers were produced by aminosilane-disilanol polycondensation reactions between a series of oligomeric, hydroxy-terminated silarylene-siloxane prepolymers and l,4-bis(dimethylaminodimethylsilyl)butadiyne [(CH3)j N-Si(CH3)3-C -C=C-(CH3)3Si-N(CH3)3]. The oligomeric, hydroxy-terminated...
