Title
(EN) MATERIALS COMPRISING A MATRIX AND PROCESS FOR PREPARING THEM
Abstract
(EN)

The present invention is concerned with particulate material having a number average particle diameter of 1 μm-1 cm, exhibiting a solid-solid phase change, as measured by differential scanning calorimetry (DSC), in the temperature range −10° C. to +100° C. and comprising:

    • a matrix material comprising a plurality of urethane and/or urea and/or isocyanurate groups and having a hardblock content of more than 75% (hereinafter called matrix A); and
    • a polymeric material. Process for making this material and the use of it as.
