<p>The present invention relates to a siloxane of formula where F1 is a functional group attached directly to Q or bonded via an intermediate group; Q is a substituted or unsubstituted aromatic group; D is unsubstituted or substituted hydrocarbylene; R1, R2, R3, R4, R5 and R6 are each independently unsubstituted or substituted hydrocarbyl; x, y and z each independently has a value from 0 to 100. These polysiloxane monomers are prepared by reacting a compound of formula F1 - Q - Z - M wherein F1, Q and Z are as defined above and M is an alkali or alkaline earth metal, with a disiloxane of formula ?ein R1 and D are as defined above and X is C1, Br or I, ? the presence of a dipolar aprotic liquid, a phase 1338 DIV. I transfer catalyst or combination thereof. The monomers are useful in the preparation of polymers with improved solubility and adhesion and which are useful, among other things, as protective coatings.</p> |
