Abstract
This invention relates to a polymerization process for producing a polyketoester, or an olefin-polyketoester utilizing a hydroesterification catalyst and an olefin-CO copolymerization catalyst in a reaction medium. Polyketoester copolymers and olefin-polyketoester copolymers are also disclosed.
Claims29
A polymerization process comprising:
- contacting an alpha-omega enol having the general formula:
- wherein R* is a divalent hydrocarbyl, a divalent hydrocarbyl substituted with one or more functional group comprising elements from Group 13-17 of the periodic table of the elements, or a combination thereof;
- and carbon monoxide (CO) in the presence of a hydroesterification catalyst and an olefin-CO copolymerization catalyst in a reaction medium within a reactor at a temperature, a CO pressure, and for a period of time sufficient to produce a polyketoester having an empirical formula:
- (A)a(B)b(C)c(D)d
- wherein a>0, b≥0, c>0, and d≥0;
- moieties A, B, C, and D may be arranged randomly, in blocks, or in any order;
- moiety A having the general formula:
- moiety B having the general formula:
- moiety C having the general formula:
- and
- moiety D having the general formula:
- wherein R++ is H, or a polyketoester chain having the empirical formula (A)a(B)b(C)c(D)d;
- wherein a>0, b≥0, c>0, and d≥0.
