A method of curing a curable composition includes: providing the curable composition; providing a substrate having a primer disposed on at least a portion thereof, wherein the primer comprises at least one immobilized polyvalent metal compound for free-radically curing the curable composition; and contacting the curable composition with the primer, thereby causing at least partial curing of the curable composition. The curable composition includes at least one free-radically polymerizable compound and a beta-dicarbonyl compound. The method can be used for adhesive bonding of substrates and preparation of various articles.

Catalyst systems and methods for making and using the same. A method for making a catalyst support includes forming a mixture of a support material and a fluoride donor. The mixture is added to a fluidized bed reactor. The mixture is fluidized to form a fluidized bed with a height to diameter ratio of at least about 2.3. The mixture is calcined to decompose the fluoride donor, forming a fluorinated support.
