Abstract

Continuous evaporation or heat treatment of elastomers and thermoplastics is carried out in a mixer and kneader fitted with stirring shafts (7 - 10) on which mixing and kneading components (11) are mounted. New low viscosity solution is mixed with pre-evaporated viscous material, the viscosity and concentration of the solution being adjusted so that the energy input from mechanical kneading and heat transfer is maximised. An Independent claim is included for apparatus for carrying out the process with an inlet (5) for solution connected to a mixer/kneader (1) with good back mixing connected to a second mixer/kneader (2) with good forced flow.
