摘要： An anion exchange membrane is composed of a copolymer of 1,1-diphenylethylene and one or more styrene monomers, such as 4-tert-butylstyrene. The copolymer includes a backbone substituted with a plurality of ionic groups coupled to phenyl groups on the backbone via hydrocarbyl tethers between about 1 and about 7 carbons in length. High-temperature conditions enabled by these copolymers enhance conductivity performance, making them particularly suitable for use in anion exchange membranes in fuel cells, electrolyzers employing hydrogen, ion separations, etc. The properties of the membranes can be tuned via the degree of functionalization of the phenyl groups and selection of the functional groups, such as quaternary ammonium groups. Several processes can be used to incorporate the desired ionic functional groups into the polymers, such as chloromethylation, radical bromination, Friedel-Crafts acylation and alkylation, sulfonation followed by amination, or combinations thereof.

摘要： Chewing gums and chewing gum bases which are cud-forming and chewable at mouth temperature contains a multi-block copolymer having at least two repeating sequences of at least two different polymeric blocks having at least three monomer units each. The multi-block copolymer optionally includes linking units and may be formulated to have non-covalent crosslinking between the copolymer chains. The multi-block copolymer is optionally plasticized with a compatible di-block copolymer to function as an elastomer system in the gum base. Characteristics of the multi-block copolymers can be selected to produce gum bases and chewing gums having desired properties. In some cases, chewed cuds formed from the gum bases may exhibit improved removability from environmental surfaces to which they may become undesirably attached.

摘要： A magnetic resonance imaging apparatus that carries out a pulse sequence for making a signal of a first substance within an object smaller than a signal of a second substance within the object. The pulse sequence includes an α°-pulse for exciting the object, a refocus pulse for refocusing a phase of spin within a region excited by the α°-pulse, and a readout gradient field for acquiring a magnetic resonance signal from the region. The α°-pulse has a spectral selectivity such that a transverse magnetization of the first substance is made smaller than a transverse magnetization of the second substance. The refocus pulse has a spectral selectivity such that a phase of spin of the second substance is refocused and refocusing of a phase of spin of the first substance is suppressed.

摘要： An ethylene-based copolymer for non-crosslinked water supply pipe is provided. The ethylene-based copolymer is prepared using a supported hybrid metallocene catalyst and has a dimodal or broad molecular weight distribution. The ethylene-based copolymer has a high density molecular structure in a low molecular weight and has a low density molecular structure with high content of a comonomer in a high molecular weight. The ethylene-based copolymer has a molecular weight distribution of 5-30 and the distribution of copolymerization of ethylene and C3-20 α-olefin is localized in high molecular weight chains. Accordingly, the ethylene-based copolymer has superior processability, internal pressure creep resistance at high temperatures and environmental stress crack resistance.

摘要： An anion exchange membrane is composed of a copolymer of 1,1-diphenylethylene and one or more styrene monomers, such as 4-tert-butylstyrene. The copolymer includes a backbone substituted with a plurality of ionic groups coupled to phenyl groups on the backbone via hydrocarbyl tethers between about 1 and about 7 carbons in length. High-temperature conditions enabled by these copolymers enhance conductivity performance, making them particularly suitable for use in anion exchange membranes in fuel cells, electrolyzers employing hydrogen, ion separations, etc. The properties of the membranes can be tuned via the degree of functionalization of the phenyl groups and selection of the functional groups, such as quaternary ammonium groups. Several processes can be used to incorporate the desired ionic functional groups into the polymers, such as chloromethylation, radical bromination, Friedel-Crafts acylation and alkylation, sulfonation followed by amination, or combinations thereof.
