The invention relates to a process for producing polyarylene ether beads from a polyarylene ether solution, comprising the steps of

Division of a polyarylene ether solution

The present invention relates to a coarsely divided microcapsule preparation with particles whose particle sizes are in the range from 200 &#x3bc;m to 5 cm, comprising microcapsules with a capsule core of latent heat storage material and a thermosetting polymer as capsule wall and one or more polymeric binders whose binder polymer has thermoplastic properties and film-forming properties under processing conditions, where the binder content, calculated as solid, is 1-30% by weight, based on the total weight of the coarsely divided microcapsule preparation.

Coarse-particle microcapsule preparation

The present invention relates to a coarse-particled microcapsule preparation comprising microencapsulated latent heat accumulators and one or more polymeric binders, the ratio of surface area to volume of the particles obeying the following relationship: and to processes for its production and its use in heat exchangers and building materials.
