Abstract
Methods of producing plant polyols from plant oils include reacting a plant oil with a designed reactant having one or more nucleophilic functional groups and one or more active hydrogen functional groups in the presence of an addition reaction catalyst in a single reaction step. The resultant polyols may be directly reacted with polyisocyanates to produce polyurethanes.
Claims35
A process of making a modified plant-based polyol comprising:
- a) reacting the following components in the presence of an addition reaction catalyst:
- i) at least one plant oil having at least one carbon-carbon double bond;
- and
- ii) a reactant having at least one nucleophilic functional group and at least one active hydrogen functional group.
A process of preparing a polyurethane comprising the steps of:
- a) reacting at least one plant oil having at least one carbon-carbon double bond with a reactant having at least at least one nucleophilic functional group and at least one active hydrogen functional group, the reaction performed in the presence of an addition reaction catalyst to form a plant polyol;
- and
- b) reacting the plant polyol formed in step a) with an isocyanate.
A reaction product of at least one plant oil having at least one carbon-carbon double bond with a reactant having at least one nucleophilic functional group and at least one active hydrogen functional group, the reaction performed in the presence of an addition reaction catalyst.
A polyurethane formed by a reaction mixture of
- a) an isocyanate;
- and
- b) a reaction product of at least one plant oil having at least one carbon-carbon double bond with a reactant of the formula N-AH wherein N is a nucleophilic functional group and AH is a functional group having at least one active hydrogen.
