Abstract
The present invention relates to a compound according to Formula (3), wherein the compound comprises from 28 wt. % to 100 wt. % bio-based carbon content, relative to the total mass of carbon in the compound, measured according to standard ASTM D6866-12, Method B; and wherein X+is a proton. The present invention also relates to a polymer obtained by polymerising at least one of compound according to Formula (3), in addition to processes and uses related thereto.
Claims20
A compound according to Formula (3), wherein the compound comprises from 28 wt. % to 100 wt. %, bio-based carbon content, relative to the total mass of carbon in the compound, according to standard ASTM D6866-12, Method B, calculated by multiplying the percent modern carbon value, as determined by measuring the carbon-14 content relative to the total carbon content, by a correction factor of 0.95;
- and wherein X+ is a proton.
A compound, according to Formula (3), derived from isobutene, wherein the isobutene has at least 90 wt. % bio-based carbon content, relative to the total mass of carbon in isobutene, according to standard ASTM D6866-12, Method B, calculated by multiplying the percent modern carbon value, as determined by measuring the carbon-14 content relative to the total carbon content, by a correction factor of 0.95;
- and wherein X+is a proton.
A compound, according to Formula (3), derived from acrylonitrile, wherein the acrylonitrile has at least 90 wt. % bio-based carbon content, relative to the total mass of carbon in acrylonitrile, according to standard ASTM D6866-12, Method B, calculated by multiplying the percent modern carbon value, as determined by measuring the carbon-14 content relative to the total carbon content, by a correction factor of 0.95;
- and wherein X+is a proton.
A polymer prepared by polymerising at least one compound according to Formula (3), wherein the at least one compound according to Formula (3) comprises from 28 wt. % to 100 wt. %, bio-based carbon content, relative to the total mass of carbon in the compound, according to standard ASTM D6866-12, Method B, calculated by multiplying the percent modern carbon value, as determined by measuring the carbon-14 content relative to the total carbon content, by a correction factor of 0.95;
- and wherein X+is a proton.
A process for synthesizing a compound according to Formula (3), comprising reacting acrylonitrile, fuming sulfuric acid and isobutene in a solvent;
- wherein the isobutene has at least 90 wt. % bio-based carbon content, relative to the total mass of carbon in isobutene, measured according to standard ASTM D6866-12, Method B, calculated by multiplying the percent modern carbon value, as determined by measuring the carbon-14 content relative to the total carbon content, by a correction factor of 0.95;
- and/or wherein the acrylonitrile has at least 90 wt. % bio-based carbon content, relative to the total mass of carbon in acrylonitrile, measured according to standard ASTM D6866-12, Method B, calculated by multiplying the percent modern carbon value, as determined by measuring the carbon-14 content relative to the total carbon content, by a correction factor of 0.95;
- and wherein X+is a proton.
