Patent ID: 8883876

Claim:
A method of providing a polymerized dental material comprising: a) providing as a first paste an unpolymerized first component comprising: i) a salt of a CH-acid compound, wherein said CH-acid compound has an acid strength and is able to initiate a radical polymerization, and ii) monomers polymerizable under radical conditions, wherein said first paste is stable on storage at ambient temperature for more than 6 months; b) providing as a second paste an unpolymerized second component comprising: i) an acid having an acid strength that is greater than the acid strength of the CH-acid compound present as a salt in said first component, and ii) monomers polymerizable under radical conditions; and c) mixing said first paste and second paste at a ratio of 1:1 under conditions such that said monomers polymerizable under radical conditions polymerize.
