    FT-IR studies of the polymeric binder BioCo1 with modified biopolymer. Part 1
    (2014) Grabowska, Beata; Kaczmarska, Karolina
    The paper presents structural studies of polymeric water soluble compositions consisting of acrylic derivatives/modified biopolymer. The research FT-IR was focused on novel polymer composition poly(acrylic acid)/modified starch (PAA/CMS) designed for application in the foundry industry - a novel group of polymeric BioCo binders. It was found, that the structure changes occur within groups: carboxyl present in poly(acrylic acid) and carboxyl and hydroxyl groups contained in carboxymethyl starch (vibrations: $ν_{s}$-C=O, $ν_{s}$-$COO^{-}$ and δ-C-O-H).
