<title>Effect of molecular weight distribution on the dissolution properties of novolac blends</title>

Abstract

The dissolution properties of nearly monodisperse fractions of metacresol novolac resin in aqueous potassium hydroxide solutions has been investigated. A relationship between the molecular weight of the fractions and dissolution rate was examined for a range of developer concentrations. Deliberate and calculated blending of the various fractions afforded an opportunity to investigate the fundamental relationship between molecular weight and dissolution characteristics over a range of developer concentrations.
