Abstract
A terminally-functionalized derivative of a cashew nut shell liquid (CNSL) compound, a method to form a polymer, and an article of manufacture comprising a polymer derived from the terminally-functionalized CNSL derivative. The terminally-functionalized CNSL derivative has two, three, four, or five reactive functional groups. The polymer is prepared by obtaining CNSL compounds, reacting the CNSL compounds to form the terminally-functionalized CNSL derivative, and polymerizing the terminally-functionalized CNSL derivative.

A compound having the structure:
- wherein R, R′, R″, Q, and Q′ are hydroxyl groups.
A method, comprising:
- obtaining a cashew nutshell liquid (CNSL) compound;
- converting sidechain alkene moieties on the CNSL compound to alkyne moieties to form an alkyne CNSL derivative;
- reacting the alkyne CNSL derivative with a base to form a terminal alkyne CNSL derivative;
- hydroxylating the terminal alkyne CNSL derivative to form a terminal polyol CNSL derivative;
- and
- polymerizing the terminal polyol CNSL derivative.
An article of manufacture comprising a polymer, the polymer comprising:
- a number (n) of repeat units derived from a terminally-functionalized cashew nutshell liquid (CNSL) derivative having the structure:
- wherein R, R′, R″, Q, and Q′ are hydroxyl groups.
