Object of the invention is a process for drying polychloroprene wherein hot air is blown onto both sides of the moist polychloroprene sheet. Optionally the moist sheet is exposed to infrared rays also. A further object of the invention is the dryer consisting of a warm air section and an air cooling section and optionally an infrared section.

Process and a dryer for drying polychloroprene sheets

Object of the invention is a process for polymerizing chloroprene in aqueous emulsion in a certain apparatus which prevents formation of deposits and so-called 'popcorn' polymers.

Process for the production of polychloroprene

A process for the production of partially or completely hydrolyzed ethylene/vinyl acetate copolymer which is suitable for the various powder coating techniques, wherein the polymer solution is extruded in a non-gelled state into water with a temperature no more than 20.degree. C below the gellation temperature and the gelling solution is converted into particles from 0.02 to 5 mm in diameter by means of high shear forces.
