New methods of synthesizing new types of plant derived high molecular weight polyols are provided.

Method for synthesizing high molecular weight natural oil polyols

Methods of one-pot synthesis of high molecular weight natural oil polyols having a functionality of between about 4 and about 8 are provided. The resultant polyols may be directly reacted with polyisocyanates to produce polyurethanes.

Method of synthesizing tuneably high functionality in high molecular weight natural oil polyols

A method of forming a stable mixture of a natural plant oil polyol and a petroleum-based polyol, including mixing a natural plant oil polyol with a monoglyceride, followed by adding a petroleum based polyol. Stabilized mixtures of plant oil and petroleum-based polyols can be used for synthesis of polyurethanes.

Method for increasing miscibility of natural oil polyol with petroleum-based polyol

Methods of one-pot synthesis of high molecular weight natural oil polyols having a functionality of at least two are provided. The resultant polyols may be directly reacted with polyisocyanates to produce polyurethanes.

Method for providing higher molecular weight natural oil polyols without loss of functionality

Methods of producing a hybrid petro-plant oil polyol having a high bio-content by coupling a petro-chemical polyol with a plant oil based polyol is provided, including coupling an intermediate petro-polyol prepolymer with a plant oil polyol so as to synthesize a hybrid petro-plant oil polyol having a high bio-content and a hydroxyl number of between about 50 and 60.

High bio content hybrid natural oil polyols and methods therefor

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.

Polyols from plant oils and methods of conversion

Methods of coupling plant oil based polyols so as to synthesis high molecular weight plant oil polyols having a hydroxyl number between from about 40 to about 60. The resultant polyols may be directly reacted with polyisocyanates to produce polyurethanes.

Coupling method for providing high molecular weight natural oil polyol

A one component moisture-curing polyurethane adhesive composition having a long pot life that does not cause its user to experience breathing difficulty is described. In one embodiment the adhesive is prepared from a mixture of a high molecular weight component selected from the group consisting of polyols, diamines, and mixtures thereof; an isocyanate; and a low molecular weight component selected from the group consisting of diols, diamines, and mixtures thereof.
