Abstract
A continuous process for functionalizing olefins, especially polymer olefins in a CSTR or pipe reactor. Esters are preferably produced by continuous reaction of the olefin with carbon monoxide and a nucleophilic trapping agent. The liquid-filled pipe reactor operates in plug flow with static mixers and the CSTR is operated in the substantial absence of air at constant liquid level.
Claims29
A process for producing a functionalized polymer comprising continuously (A) reacting a polymeric olefin, a nucleophilic trapping agent of formula HYR.sup.3 and gaseous carbon monoxide in the presence of an acid catalyst and in the absence of reliance on transition metal catalyst, whereby said polymeric olefin is functionalized by attachment of --CO--YR3 groups, wherein Y is O or S, and R.sup.3 is H, hydrocarbyl, aryl, substituted aryl or substituted hydrocarbyl;
- and (B) recovering functionalized polymer.
A process for producing a functionalized olefin comprising continuously reacting a liquid-phase olefin with gaseous carbon monoxide and a nucleophilic trapping agent of formula HYR.sup.3 in the presence of an acid catalyst, wherein said olefin is functionalized by attachment of --CO--YR.sup.3 groups wherein Y is O or S, and R.sup.3 is H, hydrocarbyl, aryl, substituted aryl or substituted hydrocarbyl, and wherein the process is conducted in a pipe reactor containing static mixers to disperse gas into liquid for reaction, the process being operated in laminar flow.
