PROCESS FOR THE POLYMERISATION OF VINYL CHLORIDE IN SUSPENSION |
摘要 |
The technical problem of the suspension polymerisation of vinyl chloride, alone or in a mixture with other monomers, without it being adversely affected by the formation of encrustations in the polymerisation reactor, is solved by carrying out the polymerisation in the presence of a mixture of polyvinyl alcohols having a mean saponification number between 300 and 500, accompanied by substances of hydroxylic character, such as clays, bentonites and natural or artificial inorganic colloids. |
