Abstract
Abstract Improved organic aldehyde and ketone peroxide compositions useful for initiating the polymerization of polyesters formed from the concurrent reaction of a beta dione such as 2,4-pentanedione and a different (non-beta dione) ketone or aldehyde, for example methyl ethyl ketone, with aqueous hydrogen peroxide.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
132 words
An organic peroxide especially suitable for the room temperature curing of polyester resins made by the process comprising: concurrently reacting a beta dione of up to about 20 carbon atoms of the structure: ##EQU2## in which R 1 and R 2 are individually selected from the group consisting of alkyl, cycloalkyl, and aryl with a different carbonyl compound selected from the group consisting of ketones and aldehydes of up to about 20 carbon atoms free from aliphatic unsaturation and containing only carbon, hydrogen, and oxygen in a ratio of 1 mole of beta dione to about 3-20 equivalent weights of said different carbonyl compound based upon the number of co-reactive carbonyl groups therein in an acidic hydrophilic fluid media containing sufficient aqueous hydrogen peroxide to form appreciable amounts of organic peroxides therewith.
Claim 2
Dependent Claim
