The effect of 2-Chloro-1,3,2-dioxaphospholane on the AIBN initiated polymerisation of acrylo - nitrile, methyl methacrylate and styrene was investigated kinetically in benzene at 60 - 80°C. With acrylonitrile normal kinetic orders with respect to monomer and AIBN could be observed with the phospholane behaving as a chain transfer agent. With methyl methacrylate and styrene it was observed that the phospholane causes enhancement of the rates due to concurrent radical and ionic polymerisation besides functioning as a chain transfer agent. © 1980 Springer-Verlag.

Effect of 2-Chloro-1,3,2-dioxaphospholane on the radical polymerisation of acrylonitrile, styrene and methyl methacrylate

Polymer Bulletin

The effects of C6H5PCl2, POCl3, and PCl3 on the free radical polymerisation of acrylonitrile initiated by a,a′-azobisisobutyronitrile were kinetically investigated in benzene and trichloroethylene solutions. With PCl3 rates of polymerisation were unaffected but the degrees of polymerisation were found to decrease with increasing PCl3. With C6H5PCl2 and POCl3 however both rates and degrees of polymerisation were adversely affected. Thus PCl3 acts as a chain transfer agent while the other two phosphorous compounds function as degradative chain transfer agents. © 1980 Springer-Verlag.
