The present invention is directed to renewable compositions derived from fermentation of biomass, and integrated methods of preparing such compositions.

Renewable compositions

Isobutene, isoprene, and butadiene are obtained from mixtures of Cand/or Colefins by dehydrogenation. The Cand/or Colefins can be obtained by dehydration of Cand Calcohols, for example, renewable Cand Calcohols prepared from biomass by thermochemical or fermentation processes. Isoprene or butadiene can be polymerized to form polymers such as polyisoprene, polybutadiene, synthetic rubbers such as butyl rubber, etc. in addition, butadiene can be converted to monomers such as methyl methacrylate, adipic acid, adiponitrile, 1,4-butadiene, etc. which can then be polymerized to form nylons, polyesters, polymethylmethacrylate etc.
