It is well known that it is not possible to carry out O-alkylation (except
methylation, benzylation, allylation and acetylation) in case of β,β-disubstituted
hydroxy compounds due to steric constrains. In this invention we have developed
a process to carry out the O-alkylation in case of β,β-disubstituted hydroxy
compounds using various alkyl groups. This enables us to design and synthesize
variety of functional compounds which then can be used for the syntheses
of functional polymers.
The invention relates to methods for the synthesis of O-alkylated functional
monomers of formula I using β,β-disubstituted hydroxy compounds
and functional polymers. Further the invention provides methods for synthesis
of the polymers
using the O-alkylated β,β-disubstituted hydroxy compounds.
