Abstract

Rotation mouldings incorporating >=2 significantly different resins in layers formed pref. due to differential particle sizes used for the differing ingredients. The component resins may be introduced together or successively. Pref. the particle size distributions of the component materials have some adjacent or overlapping values to ensures physical mixing at interfacial zones. Used to obtain a cast moulding with a cured thermosetting skin and a thermoplastic lining, from finely divided thermosetting resins with coarser thermoplastic resins and a stratified structure of A/B/A/B/A (where A is thermosetting layer and B is thermoplastic layers. Pref. a mould release agent is used.
