Abstract

1,131,587. Polymerizing vinyl chloride. PRODUITS CHIMIQUES PECHINEYSAINT-GOBAIN. 28 June, 1967 [28 June, 1966], No. 29792/67. Heading C3P. A two-stage bulk polymerization of vinyl chloride is effected in the first stage with a high degree of turbulence under hot conditions (20-75‹ C. and 2-14 bars) with a catalyst of short half life and in the second with low agitation under cold conditions (- 60‹ to + 20‹ C. and 65 mm. mercury-2 bars) in the presence of added catalyst and a C 1 -C 4 aliphatic alcohol and optionally a halogencontaining chain length regulator. The first stage may be applied to only part of the monomer. The first stage catalyst is sulphonyl cyclohexane acetyl peroxide, isopropyl peroxydicarbonate or ethyl-hexyl peroxy-dicarbonate and in the second stage is used hydrogen peroxide, ferric sulphate and ascorbic acid or a peroxide and a trialkyl boron-hydrazine complex optionally with oxygen. The alcohol is methanol, ethanol or isopropanol. Apparatus and methods of Specification 1,040,114 are used.
