Abstract
An alkoxylated bio-oil composition is provided. The alkoxylated bio-oil composition may include an alkoxylated bio-oil prepared from an alkoxylation of dewatered bio-oil. A method for preparing an alkoxylated bio-oil composition is provided. A copolymer composition is provided. The copolymer composition may include an alkoxylated bio-oil copolymer unit. A method for preparing a copolymer composition is provided.
Claims16
A copolymer composition, comprising:
- a copolymer comprising:
- an alkoxylated bio-oil unit, the alkoxylated bio-oil unit derived from an alkoxylated bio-oil composition comprising an alkoxylated bio-oil having a hydroxyl value of at least 415;
- and
- a cross-linking unit, the cross-linking unit derived from a crosslinking reagent and effective to crosslink more than one alkoxylated bio-oil unit to form the copolymer
- wherein the alkoxylated bio-oil is derived from direct alkoxylation of a dewatered bio-oil using an alkoxylation reagent consisting of:
- an epoxide and a cyclic carbonate in the presence of a promoter, the dewatered bio-oil is obtained by dewatering a bio-oil, and further wherein the bio-oil is obtained from the pyrolysis of wood or other lignocellulosic-containing biomass.

A method for preparing a copolymer composition, the method comprising:
- providing a polymerization precursor mixture, the polymerization precursor mixture comprising a crosslinking reagent configured to form a copolymer in combination with an alkoxylated bio-oil having a hydroxyl value of at least 415, wherein the alkoxylated bio-oil is derived from direct alkoxylation of a dewatered bio-oil using an alkoxylation reagent consisting one of:
- an epoxide and a cyclic carbonate in a presence of a promoter, the dewatered bio-oil is obtained by dewatering a bio-oil, and further wherein the bio-oil is obtained from pyrolysis of wood or other lignocellulosic-containing biomass;
- and
- reacting an alkoxylated bio-oil composition comprising the alkoxylated bio-oil with the polymerization precursor mixture under reaction conditions effective to form the copolymer composition, wherein the cross-linking agent in the precursor mixture is derived from a crosslinking reagent and effective to crosslink the alkoxylated bio-oil to form the copolymer.
