Synthesis of Polymers From Bio-Based Methacrylates Comprising Aromatic or Aliphatic Structures Using NIR-Mediated ATRP.

ABSTRACT: NIR-mediated ATRP is used for the synthesis of polymethacrylates from the bio-based monomers 4-(4-methacryloyloxyphenyl)butan-2-one and methyl 9-hydroxy-10-(methacryloyloxy) octadecanoate / methyl 9-(methacryloyloxy)-10-hydroxy octadecanoate. According to the NIR-mediated ATRP protocol, excitation is carried out at 790 nm in the presence of copper(II)bromide tris(2-pyridylmethyl)amine complex as deactivator and a heptamethine cyanine comprising a barbiturate group in the meso-position operating as sensitizer. The homopolymers obtained are compared with similarly made poly(methyl methacrylate) regarding yield, molecular weight, dispersity, and glass transition temperature. Furthermore, block copolymers made from methyl methacrylate and the bio-based monomers are included in this comparison.
