摘要:
Photoiniferters for controlled radical polymerizations are described. The photoiniferters have an azlactone or ring-opened azlactone moiety to provide telechelic (co)polymers.
摘要:
The present invention provides novel compositions prepared from a first oligomer containing reactive functional groups capable of reaction at effective rates (at normal processing temperatures) with a co-reactive second component oligomer possessing functionality that is complementary to that of the first oligomer. The compositions may be used as coatings, including hard surface coatings, clear coatings, powder coatings and pattern coatings; as adhesives, including pressure sensitive adhesives and hot melt adhesives; as sealants; as optical coatings; as blown microfibers (BMF); as high refractive index optical materials; as barrier films; in microreplication; as low adhesion backsizes, (LABs) and as release coatings.

Chain transfer agents for controlled radical polymerizations (RAFT) are described. The chain transfer agents have an azlactone or ring-opened azlactone moiety to provide telechelic (co)polymers.
摘要:
Organic polymers for use in electronic devices, wherein the polymer includes repeat units of the formula: 1 wherein: each R1 is independently H, an aryl group, Cl, Br, I, or an organic group that includes a crosslinkable group; each R2 is independently H, an aryl group or R4; each R3 is independently H or methyl; each R5 is independently an alkyl group, a halogen, or R4; each R4 is independently an organic group that includes at least one CN group and has a molecular weight of about 30 to about 200 per CN group; and nnull0-3; with the proviso that at least one repeat unit in the polymer includes an R4. These polymers are useful in electronic devices such as organic thin film transistors.

Initiators for atom transfer radical polymerizations are described. The initiators have an azlactone or ring-opened azlactone moiety to provide telechelic (co)polymers.
摘要:
A dry-strippable coating composition can be incorporated into a composite article and comprises a dried water-borne polyurethane dispersion including a release additive comprising a releasing co-solvent or other selected release material. When water is removed from the polyurethane dispersion of the composite article and when the article comprises a thermoformable substrate, the article can be thermoformed to provide a shaped article. Dry-stripping the coating composition from the substrate provides a thermoformed substrate and a thermoformed protective layer. The dry-strippable coatings provide temporary protection for the surface of various products and components during manufacture, assembly, shipping, installation, painting, and refinishing operations.
摘要:
A composition in the form of an aqueous dispersion used in cosmetic applications is provided. The composition comprises at least one polyurethane-urea polymer that is functionalized with at least one hydrolyzed or hydrolyzable silyl group. When the composition is used in hair care, it does not have a reshapable effect.
