Abstract
Processes to prepare lightly branched surfactant products comprise combining at least one olefin and a coordination-insertion catalyst under conditions such that at least one oligomer product is formed. The surfactant products comprise a main carbon chain containing an average of between 0.5 and 2.5 branches, wherein more than 50% of the branches are ethyl branches, wherein the branches are located more than one carbon away from each end of the main carbon chain in more than 20% of surfactant product molecules.
