synthesizes the first hyperbranched analogs of linear poly meth acrylates including those of the conventional monomers such as methyl using inimers which produce a polymer with an ester group attached to every other carbon along the polymer backbone with a non functionalized alkyl ester attached as a free side chain the present invention synthesizes the inimer from halohydrin eg bromohydrin in higher yields by converting the amine group of serine or its derivatives into halogen by diazotization reaction in the presence of halogen containing salts eg kbr for the purpose of this application an u201c inimer u201d is a molecule having a vinyl group and an initiating group which will initiate polymerization of the molecule this step was followed by esterification of the alcohol of the desired functional group required in the polymer this hydroxy group containing ester was further esterified with acryloyl chloride or acrylic anhydride using triethylamine as a reagent in the case of bromohydrin based esters acrylic anhydride was used for the esterification to avoid any halogen exchange of the halogen group br to cl which occurred when acryloyl chloride was used in esterification and this was confirmed with electron ionization mass spectroscopy and 13 c nmr spectroscopy during the polymerization of the inimer by atrp decomposition of the inimer was confirmed by 1 h nmr and 13 c nmr spectroscopy and occurred when free ligand not complexed with the copper catalyst of the higher basicity such as n n n u2032 n u2032 pentamethyldiethylenetriamine pmdeta was present in the reaction system this was avoided by performing a catalyst ligand complex first and subsequently adding the inimer into the reaction mixture this decomposition also did not occur if a ligand of low basicity 2 2 u2032 dipyidine was used.
