Abstract:

Comb methyl allyl polyethenoxy etherpolymethyl acrylate (HPEG/PMA) was synthesized with atom transfer radical polymerization (ATRP). FT-IR and ¹H NMR were used to identify the structure of HPEG/PMA. The results show that we successfully synthesized  comblike HPEG/PMA. Gel permeation
chromatography (GPC) was used to characterize the molecular weight and molecular weight distribution. The molecular weight was 7.7×10³ and molecular weight distribution was 1.11. It indicates that the synthesis of HPEG/PAA with ATRP has good controllability. The HPEG/PMA was hydrolyzed with NaOH 
V(ethanol)∶V(H₂O)=1 solution to get HPEG/PAA.

Key words: atom transfer radical polymerization (ATRP), comb structure, methy allyl polyethenoxy ether (HPEG)
