The amphiphilic copolymers with polyoxyethylene (PEO) grafts were synthesized by copolymerization of the methacrylate terminated PEO macromers with styrene(S)
methyl methacrylate(MMA) or methyl acrylate(MA) respectively
and charac terned by GPC
IR
1H-NMR
WAXD and DSC. Their crystalline properties
emulsifying properties and phase transfer catalytic effects in the Williamson reaction were studied. The crystallinity of the copolymers increases with the increase of both the content and molecular weight of PEO grafts. In the Williamson reaction both the emulsifying volume and conversion increase with the amount or PEO content of the copolymers used
but decrease with increasing molecular weight of the PEO grafts.
