摘要 |
<p>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.</p> |
