英文摘要Friedel-Crafts alkylation was employed for the preparation of benzyl chlorine-free branched poly(4-acetoxystyrene) (PSTO). Firstly, the cationic polymerization of 4-acetoxystyrene (STO) was conducted in CH2Cl2 at -15 degrees C with 1-phenylethyl chloride (St-Cl)/SnCl4/nBu(4)NBr initiating system. Then, the chlorine end-groups would further slowly undergo alkylation reactions (mainly intra-molecular) at 0 or -15 degrees C. The Friedel-Crafts alkylation can be accelerated by elevating the reaction temperature to 25 degrees C, which finally led to a complete conversion of terminal benzyl chlorine groups. H-1 NMR and Triple-detection GPC equipped with multi-angle laser light scattering detector (MALLS), a viscosity detector (VIS), and a refractive index detector (RI) revealed the occurrence of inter-molecular alkylation at 25 degrees C, which resulted in the formation of branch topology. Because of the advantages of chlorine-free and branched structures, the product is expected to be applied as photoresists to meet the requirements for high pattern resolution requirement.
