Abstract
A method of curing a free-radically polymerizable composition includes contacting a curable composition with at least one oxide of copper. The curable composition includes: free-radically polymerizable compound; and a beta-dicarbonyl compound represented by the formula (I) or a salt thereof, wherein: R1 and R2 independently represent a hydrocarbyl or substituted-hydrocarbyl group having from 1 to 18 carbon atoms; R3 represents hydrogen, or a hydrocarbyl or substituted-hydrocarbyl group having from 1 to 18 carbon atoms; and each X independently represents O, S, formula (II), or formula (III) wherein each R4 independently represents H or alkyl having from 1 to 18 carbon atoms, or taken together any two of R1, R2, R3; or R4 form a ring. Articles including the cured compositions are also disclosed.
Claims20
A method comprising:
- a) providing a curable composition comprising:
- at least one free-radically polymerizable compound;
- and
- a beta-dicarbonyl compound represented by the formula
- or a salt thereof, wherein:
- R1 and R2 independently represent hydrocarbyl or substituted-hydrocarbyl group having from 1 to 18 carbon atoms;
- R3 represents hydrogen, or a hydrocarbyl or substituted-hydrocarbyl group having from 1 to 18 carbon atoms;
- and
- each X independently represents O, S,
- wherein each R4 independently represents H or alkyl having from 1 to 18 carbon atoms, or taken together any two of R1, R2, R3, or R4 form a ring;
- and
- b) contacting the curable composition with at least one oxide of copper, thereby causing at least partial curing of the curable composition.
A method of forming an article, the method comprising:
- providing a first substrate having a surface, wherein at least a portion of the surface of the first substrate comprises at least one oxide of copper;
- and
- contacting a curable composition with the at least one oxide of copper whereby the curable composition at least partially cures, and wherein the curable composition comprises:
- at least one free-radically polymerizable compound;
- and
- a beta-dicarbonyl compound represented by the formula
- or a salt thereof, wherein:
- R1 and R2 independently represent hydrocarbyl or substituted-hydrocarbyl group having from 1 to 18 carbon atoms;
- R3 represents hydrogen, or a hydrocarbyl or substituted-hydrocarbyl group having from 1 to 18 carbon atoms;
- and
- each X independently represents O, S,
- wherein each R4 independently represents H or alkyl having from 1 to 18 carbon atoms, or taken together any two of R1, R2, R3, or R4 form a ring.
An article comprising:
- a first substrate having a surface, wherein at least a portion of the surface of the first substrate comprises at least one oxide of copper;
- and
- a reaction product of components comprising:
- the at least one oxide of copper;
- at least one free-radically polymerizable compound;
- and
- a beta-dicarbonyl compound represented by the formula
- or a salt thereof, wherein:
- R1 and R2 independently represent hydrocarbyl or substituted-hydrocarbyl group having from 1 to 18 carbon atoms;
- R3 represents hydrogen, or a hydrocarbyl or substituted-hydrocarbyl group having from 1 to 18 carbon atoms;
- and
- each X independently represents O, S,
- wherein each R4 independently represents H or alkyl having from 1 to 18 carbon atoms, or taken together any two of R1, R2, R3, or R4 form a ring.
