Abstract (en)
[origin: WO2022106534A1] Described is a graft polymer of (meth)acrylic acid(C1-C8)-alkyl ester on a graft base from the group of the acrylate rubbers for increasing reflectance and/or reducing the yellowness index of a titanium dioxide-containing thermoplastic composition. The invention describes in particular the use of the additive to improve the reflectance of polycarbonate-based reflective white compositions that can be use in the field of reflectors.
