The present invention provides a new class of thermosetting ring-opening metathesis polymerization materials based on norbornene and oxanorbornene dicarboximide moieties containing at least one acetal ester group linkage. The acetal ester group is degradable when subjected to heat or acidic aqueous hydrolysis. The polymerization materials can be used in reworkable thermosetting compositions. R1-Rs, X, and n are defined herein. 

Thermosetting ring-opening metathesis polymerization materials with thermally degradable linkages

The invention further provides hair care compositions comprising the polymers. Particularly, the hair care composition is a hair styling composition that provides hairstyle retention at a relative humidity exceeding about 40 percent. The invention furthermore provides a method of providing hairstyle retention to hair at a relative humidity exceeding about 40 percent, the method comprising applying to hair the hair care composition as described herein.

Personal care compositions comprising polymers derived from vinyl alcohol ethers and applications thereof

The invention provides polymers having the structure: wherein Q, Q', E, R, a, b, c, d, and n are described herein. The invention further provides compositions comprising the polymers such as, personal care, hair care, coatings, and battery compositions. The invention furthermore provides hair care compositions comprising the polymers described herein.

Polymers derived from amino-functional vinyl alcohol ethers and applications thereof

Provided are modified natural compounds that are produced, at least in part, from (A) at least one epoxidized and/or maleated natural fatty acid, or epoxidized and/or maleated natural oil, and (B) at least one lactam having at least one hydroxyl functional group, wherein the lactam may be in a blend with one or more optional alcohol(s). Among other properties, the modified natural compounds may exhibit dispersibility or solubility characteristics in water and/or alcohols. The invention further provides a wide variety of compositions comprising the modified natural compounds. 

Renewable modified natural compounds

The invention provides compounds and monomers having a carbonate linkage. The monomers can be used to form homopolymers or can be coupled with other monomers to provide a wide variety of non-homopolymers. The invention further provides a wide variety of compositions comprising the compounds, monomers, and polymers. In the exemplary structures below, Q, A, R, and n are as described herein. 

Compounds, monomers, and polymers containing a carbonate linkage

A ring-opening metathesis polymerization (ROMP) reaction is disclosed in which a cyclic alkene compound is subjected to ROMP using a ruthenium ROMP catalyst having heterocyclic ligands in the presence of a compound from which such ligands may be derived. The process includes the step of adding sufficient of an acyclic alkene having a carbon-carbon double bond capable of reacting with the catalytic metal moieties attached to the living end of each of the polymer chains generated in the ROMP reaction to end cap the polymer chains and to generate a olefin metathesis catalyst. The process includes reiterating the polymerization steps by adding further amounts of a cyclic alkene compound. The catalyst may be generated in situ from a precursor compound by the addition of a compound from which heterocyclic ligands may be derived by interaction with the precursor compound.

Olefin metathesis polymerisation

This invention relates to ruthenium initiators for the ring-opening metathesis polymerization (ROMP) of cyclic olefins that are inactive at room temperature but activatable at elevated temperature (referred to as ('thermally switchable'). In general, these are compounds of ruthenium metal to which are bonded four or five ligands, in which one ligand is a pyridine ring in which the nitrogen is chelated to the ruthenium, or a five or six membered ring incorporating nitrogen and the ruthenium in which the nitrogen is chelated to the ruthenium.
