A successive method for preparing novel amphiphilic graft copolymers with a hydrophilic backbone and hydrophobic side chains was developed. An anionic copolymerization of two bifunctional monomers, namely, allyl methacrylate (AMA) and a small amount of glycidyl methacrylate (GMA), was carried out in

β¦ Synopsis
A graft copolymer of polystyrene on poly(methylphenylsily1ene) was conveniently synthesised by using the bromomethyl groups of bromomethylated poly(methy1phenyk.ilylene) as initiating sites for the bulk polymerisation of styrene by an atom transfer radical mechanism.

The radical copolymerization of styrene or methyl methacrylate and diphenylvinylsilane 1 led to Si-H functionalized polyolefins 5-7 and 8-10, respectively. The efficiency of incorporation of 1 was low. In addition, the molecular weights were inversely proportional to the concentration of 1, indicati

The vinyl of the ester group of 2-vinyloxyethyl methacrylate was first selectively reacted with acetic acid to obtain 2-[1-(acetoxy)ethoxy]ethyl methacrylate ( 2). This protected monomer was subjected to anionic polymerization in tetrahydrofuran at 060ΠC in the presence of LiCl, using 1,1-diphenylhe
