REACTIONS OF CHLOROMETHYLSILANES AND SILOXANE WITH DEHYDRIC PHENOLS,
Abstract
The reaction of bis(chlormethyl) tetramethyl disiloxane and chlormethyl-dimethyl butoxysilane with resorcinol, hydroquinone or dioxydiphenyl propane(dian) was carried out in a medium of absolute butanol under nitrogen. Owing to the easy exchange of sodium between the monosodium derivative of resorcinol and the product, a mixture of oligomers was obtained - low molecular oxyphenoxymethylsiloxanes of the type HOAr/OCH2(CH3) 2SiOSi(CH3)2CH2OAR/nOH, where n = 2 - 3. Similarly, the reaction of bis(chlormethyl) tetramethyldisiloxane with monodisodium derivatives of hydroquinon and resorcinol took place. In the interaction of disodium derivatives of dian with chlormethyl-butoxysilane, the resin obtained was similar to disubstituted ester of the formula C29H48O4Si2 with an admixture of monosubstituted ester with the formula C22H32O3Si. Using the example of disubstituted esters of dian, the homocondensation of products of their hydrolysis with 18% HC1 was studied.
