Organotin polymers XIV. Synthesis and copolymerization reactions of p‐acryloyloxy‐tri‐n‐butyltin benzoate with some vinyl monomers

Abstract

Abstractp‐Acryloyloxy‐tri‐n‐butyltin benzoate (ABTB) was prepared by the reaction of p‐hydroxy‐tri‐n‐butyltin benzoate and acrylic acid in the presence of dicyclohexylcarbodiimide. The monomer reactivity ratios for the copolymerizations of ABTB (M1) with methyl acrylate (M2), ethyl acrylate (M2), n‐butyl acrylate (M2), methyl methacrylate (M2), styrene (M2) and acrylonitrile (M2) have been found to be r1 = 0.080, r2 = 1.046; r1 = 0.039, r2 = 1.585; r1 = 0.019, r2 = 2.076; r1 = 0.150, r2 = 1.710; r1 = 0.113, r2 = 1.339 and r1 = 0.007, r2 = 2.853, respectively. The Q and e values for the prepared organotin monomer were calculated. Copolymerization reactions were carried out in solution at 70°C using 1 mol‐% azobisisobutyronitrile. The structure of the ABTB monomer and the prepared copolymers was investigated by IR and 1H‐NMR spectroscopy.
