Abstract: The preparation of polyolefin foam particles of bulk density 20 - 100 g / l comprises: (A) pre-foamed particles of bulk density 120 - 400 g / l are prepared by extrusion and granulation of polyolefin containing propellent ; and (B) the particles are further foamed in one or more steps without the use of propellent, by treating with 1.5 - 8 bar steam for 5 - 120 seconds at 110 - 170 degrees C.

Abstract: The invention relates to a process for the production of styrene polymers containing water as expanding agent by suspension polymerization of styrene in the presence of an emulsifying auxiliary, the suspending agent being a mixture of water and an organic liquid which is water-miscible and which is virtually a non-solvent for polystyrene and has a boiling point below 100° C.
