Abstract:
1. A method of free radically polymerizing vinyl monomers comprising: (a) providing a non-heterogeneous mixture compromising: (b) deoxygenating the non-heterogeneous mixture if the mixture is not already deoxygenated; (c) heating the non-heterogeneous mixture to a sufficient temperature to generate sufficient initiator radicals from at least one thermal free radical initiator so as to initiate polymerization; (d) allowing the non-heterogeneous mixture to polymerize under essentially adiabatic conditions to yield an at least partially polymerized mixture; (e) adding additionally to the at least partially polymerized non-heterogeneous mixture at least one thermal free radical initiator; (f) deoxygenating the partially polymerized non-heterogeneous mixture if the mixture is not already deoxygenated; and (g) allowing the partially polymerized non-heterogeneous mixture to further polymerize under essentially adiabatic conditions to yield a further polymerized non-heterogeneous mixture; optionally wherein the non-reactive diluent is added additionally to the at least partially polymerized non-heterogeneous mixture of step (d).
