Method and composition for sterilization of a polymerizable monomer

摘要

A method is provided for sterilization of a polymerizable monomer, in which the mixture contains at least the polymerizable monomer, a compound (a), and a compound (b). Compound (a) is selected from the group of compounds (a1), compounds (a2), and compounds (a3), wherein compounds (a1) are represented by general formula (I):;
wherein R1, R2, R3, and R4, independent of each other, represent a substituted alkyl residue, a non-substituted alkyl residue, a halogen, a nitro group, or a cyano group; compounds (a2) are selected from the group of dimers of compounds (a1); and compounds (a3) are selected from the group of dialkyldicarbonates. Compound (b) is selected from the group of water and alcohols.

1. A method for sterilization of a polymerizable monomer, the method comprising mixing at least the polymerizable monomer, an acylating agent, and a compound (b), wherein:
(i) the acylating agent is selected from one of compounds (a1), (a2), and (a3), wherein compound (a1) is a compound represented by formula (I): wherein R1, R2, R3, and R4 independently represent a hydrogen, a substituted alkyl residue, a non-substituted alkyl residue, a halogen, a nitro group, or a cyano group;wherein compound (a2) is selected from the group consisting of dimers of compounds (a1); andwherein compound (a3) is selected from the group consisting of dialkyldicarbonates; and (ii) the compound (b) is selected from the group consisting of water and alcohols, thereby producing a paste, such that the polymerizable monomer is sterilized in the paste, and wherein a fraction of compound (b) in the paste is no more than 2% by weight relative to a total weight of the paste.
