H2O2 as an initiator of free-radical polymerization

Gawdzik B., Matynia T., Worzakowska M.

Polish Journal of Chemical Technology

2003

Vol. 5, nr 3

103-105

Synthesis and properties of new initiating systems formed from commercially available methyl ethyl ketone, hydroxypolyethers G 1000 and G 1002, and hydrogen peroxide (60%) are presented. Reaction was carried out in 1,2-propanodiol as a solvent. The obtained initiators with cobalt octoate as a promotor were applied for crosslinking of the commercially available unsaturated polyester resin. Properties of the resin were compared with those obtained while it was hardened by the typical curing system containing methyl ethyl ketone hydroperoxide (Luperox) and cobalt octoate.
