Reactions involving functional groups of α,ω-bis[3-(4-hydroxy-3-methoxyphenyl)propyl]oligodimethylsiloxanes

Oligomers with terminal glycidoxy or methacryloxy groups were synthesized through the interaction between α,ω-bis[3-(4-hydroxy-3-methoxyphenyl)propyl]oligodimethylsiloxanes (I) and epichlorohydrin or glycidyl methacrylate. On the basis of oligomers I with a random distribution of ≡Si-H or ≡Si-CH=CH 2 groups over macromolecular chains, organosiloxanes containing side 2-(methyldimethoxysilyl)ethyl (interaction between ≡SiCH=CH 2 and Me(MeO) 2 SiH), glycidoxypropyl (interaction between ≡Si-H and allyl glycidyl ether), or octyl (interaction between ≡SiH and 1-octene) substituents were obtained via hydride addition reactions.
