ABSTRACT:
The invention relates to a process for the preparation of suspensions of at least one polymer, said process comprising as a first step the preparation of a first suspension of at least one polymer in an organic liquid by chilling a solution of said polymer.
In accordance with the invention, there is added to the first polymer suspension in a second step a powder of at least one polymer, which may be the same as or different from the first.
Use of said process in the production of two-layer composites formed of an aluminum sheet and a polymer layer.
