Abstract

Ammonium chloride (NH4Cl) is shown to be an effective nucleating agent for poly(hydroxy butyrate) (PHB). However, NH4Cl only acts as a nucleant when it is in the face centred cubic (fcc) crystal modification. The fcc form of NH4Cl has a lattice match with PHB; thus it appears that there is some epitaxial growth of PHB crystals on to NH4Cl. Several more nitrogen-containing compounds that possess a similar lattice match have been investigated and these all show some nucleating effect.
