Abstract: Solvent-free spontaneously cross-linking highly reactive acrylic resins being crosslinkable through N-methylolether groups for powder coatings with a softening point of from 75* - 110* C are obtained from their solutions by continuous concentration through evaporation in a self-cleaning screw evaporator in which the residence times are from 2 to 6 minutes, the resin being heated both through external heating and through internal friction to a temperature not exceeding 120* C.
