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.
摘要:
The phenolic resin composition of the present invention includes a novolac-type phenolic resin, a resorcinol resin, and a curing agent, and is of a solid form. The mixing ratio of the resorcinol resin is preferably more than or equal to 1 part by mass and less than or equal to 100 parts by mass with respect to 100 parts by mass of the novolac-type phenolic resin. The mixing ratio of the curing agent is preferably more than or equal to 5 parts by mass and less than or equal to 25 parts by mass with respect to 100 parts by mass of a total amount of the novolac-type phenolic resin and the resorcinol resin. The phenolic resin cured product is obtained by heat-curing the phenolic resin composition.
