    摘要： A catalyst, co-catalyst, and/or chain transfer agent is added at a time after initiation of an addition polymerization reaction to produce a polymer product with a widened molecular weight distribution relative to having all of the components in the original reaction mixture. The catalyst, co-catalyst, or chain transfer agent may be added discretely or continuously to the reaction to produce a product with a bimodal, trimodal, or other broadened molecular weight distribution.

    摘要： A method for reducing the size of a patterned semiconductor feature includes forming a first layer over a substrate to be patterned, and forming a photoresist layer over the first layer. The photoresist layer is patterned so as to expose portions of the first layer, and the exposed portions of the first layer are removed in a manner so as to create an undercut region beneath the patterned photoresist layer. The patterned photoresist layer is reflowed so as to cause reflowed portions of the patterned photoresist layer to occupy at least a portion of the undercut region.

    摘要： The present invention provides polycarbonate polyol compositions with improved characteristics. Such polycarbonate polyol compositions are useful in thermosetting applications for the production of coatings for consumer products. The present invention provides compositions having such improved characteristics, in particular, polycarbonate polyol compositions having a glass transition temperature (Tg) from about −20° C. to about 60° C., from about −20° C. to about 50° C., or from about 0° C. to about 30° C., are particularl useful in thermosetting applications. In some embodiments, polycarbonate polyol compositions have a Tg from about −20° C. to about 3° C. In some embodiments, polycarbonate polyol compositions have a Tg from about 0° C. to about 50° C., from about 0° C. to about 50° C., or from about 10 “C. to about 40° C.

    摘要： In one aspect, the present disclosure encompasses polymerization systems for the copolymerization of CO2 and epoxides comprising 1) a catalyst including a metal coordination compound having a permanent ligand set and at least one ligand that is a polymerization initiator, and 2) a chain transfer agent having two or more sites that can initiate polymerization. In a second aspect, the present disclosure encompasses methods for the synthesis of polycarbonate polyols using the inventive polymerization systems. In a third aspect, the present disclosure encompasses polycarbonate polyol compositions characterized in that the polymer chains have a high percentage of —OH end groups and a high percentage of carbonate linkages. The compositions are further characterized in that they contain polymer chains having an embedded polyfunctional moiety linked to a plurality of individual polycarbonate chains.
