20 December 1985FTIR/ATR Studies Of Polymer Blend Films
Variable angle ATR was used to obtain a depth profile analysis of the films cast from blends of a high molecular weight styrene-acrylate copolymer colloid, an alkali soluble styrene-acrylic resin and an emulsified polypropylene. The dried films show a homogeneous distribution of the styrene-acrylate colloid particles and the solution polymer, however, the particles of polypropylene have a concentration gradient through the film thickness.
