    摘要: A polar group-containing olefin copolymer having excellent adhesion properties to metals or polar resins and excellent compatibility therewith, a process for preparing the copolymer, a thermoplastic resin composition containing the copolymer, and uses thereof. The polar group-containing olefin copolymer comprises a constituent unit derived from an □-olefin of 2 to 20 carbon atoms, and a constituent unit derived from a straight-chain, branched or cyclic polar group-containing monomer having at the end a polar group such as a hydroxyl group or an epoxy group and/or a constituent unit derived from a macromonomer having at the end a polymer segment obtained by anionic polymerization, ring-opening polymerization or polycondensation. The polar group-containing olefin copolymer can be prepared by polymerizing the α-olefin with the polar group-containing monomer and/or the macromonomer in the presence of a metallocene catalyst. The polar group-containing olefin copolymer and the thermoplastic resin composition containing the copolymer are used for films, sheets, modifiers, building/civil engineering materials, automobile exterior trim, electric/electronic parts, coating bases, compatibilizing agents, etc.

    摘要: A pyrimidinedione derivative compound has a basic backbone in which a phenyl group part and a pyrimidinedione part are linked by a linking structure comprising an alkyl chain containing two nitrogen atoms. This linking structure is represented by ##STR1## [wherein A is --(CH.sub.2).sub.n --, --CO-- or --O--(CH.sub.2).sub.m --; each of R.sup.1 and R.sup.2 is independently a hydrogen atom or a lower alkyl group which may be substituted by a hydroxyl group, or R.sup.1 and R.sup.2 may be so linked with each other as to make an alkylene chain and thus form a heterocyclic structure; R.sup.5 is a halogen atom, a hydroxyl group, a lower alkyloxycarbonyl group, a lower alkyloxy group which may be substituted by a lower alkyloxy group, or a lower alkyl group which may be substituted by a hydroxyl group, or R.sup.5 may be so linked with R.sup.1 as to make an alkylene chain and thus form a heterocyclic structure; n is 0, 1, 2 or 3 (when R.sup.5 is the hydroxyl group, n.noteq.0); m is 0, 1, 2 or 3; and k is 0, 1, 2 or 3 (however, a compound in which A is --O--(CH.sub.2).sub.m -- and R.sup.5 is the hydroxyl group is excluded from the pyrimidinedione derivative)]. The pyrimidinedione derivative and its acid addition salt are useful for a medical treatment of cardiac arrhythmias.
