The transition temperatures of Acrilan film have been determined by observing the viscoelastic behaviour in air and solutions. Two transition temperatures are observed in water, the higher being at 84°C. This is of importance in the dyeing of Acrilan fibres, and correlates more closely with dyeing properties than does the Tg observed at 56°C. Relationships between the transition temperatures and dyeing behaviour in the presence and absence of a dyeing assistant are discussed.
