摘要:
Carbamate and thiocarbamate compounds are described that comprise a polymerizable moiety and one or more free hydroxyl and/or thiol groups. Polymers may be obtained by polymerizing these carbamate and/or thiocarbamate compounds. The carbamate and thiocarbamate compounds, as well as the polymers they produce may be formulated into adhesive, agricultural, biocide, cleaning, coating, encapsulation, membrane, oilfield, performance chemical, and personal care compositions.

Disclosed are novel ultraviolet-absorbing compounds produced by two embodiments. By a first embodiment, the ultraviolet-absorbing compound is derived from at a first reactant being a UV absorber comprising a carbon-nitrogen triple bond and a second reactant having amine functionality. By a second embodiment, the ultraviolet-absorbing compound is derived from a first reactant being a UV absorber comprising amine functionality and a second reactant comprising a carbon-nitrogen triple bond. In both embodiments of the invention, the second reactant may be a small molecule, a monomer, a macromolecule, a biomolecule, or a polymer.The invention's ultraviolet-absorbing compounds are directed toward formulations and applications that serve to protect against UV radiation in any art. Exemplary uses of the ultraviolet-absorbing compounds are in adhesive, agriculture, cleaning/polishing, coating, containers, encapsulation, fragrances, imaging, hoses/tubing, household/industrial/institutional, medical, membrane, molded parts, oilfield, packaging, personal care, personal protective equipment, pharmaceutical, printing, veterinary, and wood-care applications. Highly preferred uses of the ultraviolet-absorbing compounds are in personal care and performance chemicals. wherein R═

This invention relates to oligomeric compounds that are prepared by the reaction of a dianhydride with an amino-alcohol to yield an imide-diol intermediate, which is then esterified with a carboxylic acid to form a reactive oligomer. An exemplary reaction scheme is the following:
摘要:
Isocyanurate compounds or resins have the structure (I) in which Y is an hydroxyl group —OH or a maleimide group Formula (II) provided that at least one maleimide group is present, and Q is any divalent organic moiety, aliphatic or aromatic.
摘要:
These compounds contain an oxetane functionality and a maleimide functionality. The oxetane functionality is homopolymerizable in reactions that undergo cationic or anionic ring opening, and the maleimide functionality is homopolymerizable, or polymerizable with compounds such as electron donor compounds. The dual functionality allows for dual cure processing. The compounds have the structure in which R1 is a methyl or ethyl group, R2 is a divalent hydrocarbon, X and Y independently are a direct bond, or an ether, ester, amide, or carbamate functionality, and Q is a divalent organic group, and provided that X and Y will not both be direct bonds.
