    摘要: Provided are selected types of terpolymer components comprising terpolymers having monomer units derived from ethylene (E), dicyclopentadiene (DCPD) and norbornene-based (NB) co-monomers. Such terpolymer components have certain specified amounts of each co-monomer as well as certain specified molecular weight and glass transition temperature characteristics. Terpolymer components which are derivatized by hydrogenation and/or by epoxidation and/or hydroxylation are also disclosed, as well as thermoplastic polyolefin compositions which contain the terpolymer components and which have especially desirable structural and thermal properties.Also provided are processes for preparing and derivatizing the terpolymer components herein. Such preparation processes comprise: a) contacting ethylene with a polymerization mixture comprising selected amounts of both DCPD and NB co-monomers, in the presence of a selected activated cyclopentadienyl-fluorenyl metallocene catalyst under specific polymerization conditions to thereby form the desired ethylene-dicyclopentadiene-norbornene terpolymer components within the polymerization mixture. These terpolymer components can then be subsequently derivatized by hydrogenation or functionalization of the residual double bonds therein.

    摘要: A CO2 amine scrubbing process uses an absorbent mixture consisting of an alkanolamine CO2 sorbent in combination with a non-nucleophilic base. The alkanolamine has oxygen and nitrogen sites capable of nucleophilic attack at the CO2 carbon atom. The nucleophilic addition is promoted in the presence of the non-nucleophilic, relatively stronger base, acting as a proton acceptor. The non-nucleophilic base promoter, which may also act as a solvent for the alkanolamine, can promote reaction with the CO2 at each of the reactive hydroxyl and nucleophilic amine group(s) of the alkanolamines. In the case of primary amino alkanolamines the CO2 may be taken up by a double carboxylation reaction in which two moles of CO2 are taken up by the reacting primary amine groups.

    摘要: Ionic liquids containing a cation with a potentially nucleophilic carbon atom bearing a relatively acidic hydrogen atom bonded to a potentially nucleophilic carbon atom, typically in the conjugated —NC(H)N— structure or a —NC(H)S— structure of imidazolium, imidazolidinium or thiazolium salts, can be capable of acting as sorbents for CO2 in cyclic separation processes. The ionic liquid may be used on its own, mixed with a solvent, preferably an aprotic, polar, non-aqueous solvent such as toluene, DMSO, NMP or sulfolane, or in conjunction with a non-nucleophilic nitrogenous base promoter compound having a pKa of at least 10.0 such as a carboxamidine or a guanidine.
