Abstract
A free radical polymerization process is provided which comprises polymerizing at least one radically polymerizable monomer in the presence of the multi-component liquid azo-peroxide initiator mixture under polymerization conditions to provide a radically polymerized homopolymer or copolymer, the multi-component liquid azo-peroxide initiator mixture comprising (a) at least 6 different azodinitriles; and (b) one or more liquid organic peroxides. Also provided is the stable multi-component liquid azo-peroxide initiator mixture.
Claims32
A free radical polymerization process comprising the step of polymerizing at least one radically polymerizable monomer in the presence of a multi-component liquid azo-peroxide initiator mixture under polymerization conditions to provide a radically polymerized homopolymer or copolymer, the multi-component liquid azo-peroxide initiator mixture comprising:
- (a) at least 6 different azodinitriles;
- and
- (b) one or more liquid organic peroxides.
A multi-component liquid azo-peroxide initiator mixture comprising:
- (a) at least 6 different azodinitriles;
- and
- (b) one or more liquid organic peroxides.
In a process for the free radical polymerization of at least one radically polymerizable monomer to provide a polymerized homo- or copolymer employing as a liquid free radical initiator mixture, at least six different azodinitriles, wherein the improvement comprises substituting at least part of the azodinitrile mixture with at least one liquid organic peroxide.
