Hydrolysisofthreepolymerizablealkoxysilanes,i.e.vinyltri(β-methoxy)silane(A172),vinyltriethoxy,silane(VTES)andγ-methacryloxypropyltrimethoxysilane(A174)underdifferentpHwascharacterized.Results,revealedthatA172wasmorequicklyhydrolyzedatalltestedpHthantheothers.Fortheother2alkoxysilanes,,hydrolysiswaspHdependant,andthelowesthydrolysiswasobservedaroundpH8.Usingthesetwo,alkoxysilanes,ambienttemperatureself-crosslinkingacryliclatexeswerepreparedthroughemulsion,polymerizationwithpHcontrolledaround8.Dependencesofthelatexandpolymerpropertiesonthesesiloxanes,andontheirincorporatedamountsinthepolymerswerestudied.Latexfilmswerepreparedafterthelatexeswere,adjustedtoloworhighpHinordertoacceleratethehydrolysisofthealkoxygroupsonthelatexparticles,sothat,toachievehighcrosslinkinginthelatexfilms.Propertiesofthepolymersweresignificantlyenhancedwith,incorporationofVTESandA174. |
