Abstract
A process of forming a polyurethane material includes forming an unsaturated alcohol from an unsaturated plant oil via a reduction reaction. The process includes forming an alkyne-terminated alcohol from the unsaturated alcohol and forming a polyol having two primary hydroxyl groups from the alkyne-terminated alcohol. The process further includes polymerizing a mixture that includes the polyol having the two primary hydroxyl groups to form a polyurethane material.
Claims19
A process of forming a polyurethane material, the process comprising:
- forming unsaturated alcohols from an unsaturated plant oil via a reduction reaction;
- forming alkyne-terminated alcohols from the unsaturated alcohols via an alkyne zipper reaction;
- forming polyols having two primary hydroxyl groups from the alkyne-terminated alcohols by converting alkynes of the alkyne-terminated alcohols to hydroxyl groups;
- and
- performing a polymerization reaction using a mixture that includes the polyols to form a polyurethane material.
A biorenewable polyurethane material formed by a process comprising:
- forming unsaturated alcohols from an unsaturated plant oil via a reduction reaction;
- forming alkyne-terminated alcohols from the unsaturated alcohols via an alkyne zipper reaction;
- forming polyols having two primary hydroxyl groups from the alkyne-terminated alcohols by converting alkynes of the alkyne-terminated alcohols to hydroxyl groups;
- and
- performing a polymerization reaction using a mixture that includes the polyols to form a biorenewable polyurethane material.
An acoustic dampening foam comprising:
- a petroleum-based first polyurethane material;
- and
- a second polyurethane material distinct from the first polyurethane material, the second polyurethane material formed by a process that includes:
- forming unsaturated alcohols from an unsaturated plant oil via a reduction reaction;
- forming alkyne-terminated alcohols from the unsaturated alcohols via an alkyne zipper reaction;
- forming polyols having two primary hydroxyl groups from the alkyne-terminated alcohols;
- and
- performing a polymerization reaction using a reaction mixture that includes the polyols to form a biorenewable polyurethane material, wherein the reaction mixture includes a diisocyanate material.
