Abstract

Spectra of 10 monomers and polymers of methacrylate esters and of methyl chloroacrylate have been studied between 6000‐450 cm^βˆ’1^.

A number of known regularities are confirmed. The CH~2~ and CH~3~ deformation vibrations in the 1500‐1350 cm^βˆ’1^ region of the polymer unit can be distinguished from absorptions due to the substituents. Some absorptions typical for the substituents have been confirmed between 800‐450 cm^βˆ’1^.

Absorptions due to deformation and stretching vibrations of the =CH~2~ group are readily determined in the corresponding first overtone region. An application of quantitative monomer estimation in the near infrared is reported.

Infrared spectra obtained for seven alkyl esters of heptafluorobutyric acid show that 18 vibrations of the CF3CF2CF2C02 group have characteristic frequencies in these esters, with most having average deviations of only about 1 cm-l. The relative intensities of the bands are also quite constant. The

Condensation telomerization is used for the synthesis of a new class of oligothioacrylate esters by means of the interaction of various dicarboxylic acids with thiodiglycol and methacrylic acid. During the condensation telomerization, the thiodiglycol undergoes homopoly condensation, the mechanism o
