Abstract
AbstractNovel silane‐modified polyoxyethylene ether surfactants (SMPES) were synthesized to improve the properties of water‐based silicone rubber by reacting polyoxyethylene ether, RO(CH2CH2O)nH (where R=nonylphenyl or dodecyl and n is 17 or 15), with 3‐chloropropylalkoxylsilane, ClCH2CH2‐CH2SiR1(OR2)2 or CICH2CH2CH2Si(OR2)3 (where R1=methyl and R2=methyl or ethyl). The structural characteristics of SMPES were indicated by Fourier‐transform infrared spectroscopy, proton nuclear magnetic resonance (NMR) spectroscopy, carbon NMR spectroscopy, silicon NMR spectroscopy, and electrospray ionization‐mass spectrometry. The properties of SMPES were also investigated. SMPES were found to be good emulsifiers, with a low foaming power and low cloud point. The water‐based silicone rubber prepared with SMPES exhibited a shorter tack‐free time and resistance to frosting when it contacted water.
