Abstract: A modified polyolefin resin having an intended adhesion strength to various substrates even when graft modification may be carried out by using an ?,?-unsaturated carboxylic acid derivative having a cyclic structure. The modified polyolefin resin may be a modified product of a polyolefin resin and satisfies conditions (A) to (C): condition (A)—a modifying component includes an ?,?-unsaturated carboxylic acid derivative having a cyclic structure; condition (B)—a ring-opening degree expressed by formula (1) is 40 or more; and condition (C)—the polyolefin resin includes an ethylene structural unit, ring-opening degree=modification degree K×ring-opening rate R??(1) wherein, in the formula (1), the modification degree K is a grafting weight (wt. %) of the ?,?-unsaturated carboxylic acid derivative, and the ring-opening rate R is a ring-opening rate (%) of the cyclic structure in the ?,?-unsaturated carboxylic acid derivative.

Abstract: A charging base includes: a base seat installed on a floor surface; a columnar tower part provided on the base seat; a first support provided on the tower part and capable of supporting a vertical first electric vacuum cleaner; and a second support provided on the tower part and capable of supporting a vertical second electric vacuum cleaner. An electric vacuum cleaner system includes the charging base configured as described above, the vertical first electric vacuum cleaner, and the vertical second electric vacuum cleaner.

Abstract: A sliding property improving agent comprising a multi-phase structure thermosplastic resin which consists of a dispersion of 5 to 95 parts by weight of a non-polar .alpha.-olefin polymer (a) and 95 to 5 parts by weight of a vinyl polymer (b), with the dispersing polymer having a particle size from 0.001 to 10 .mu.m. A thermoplastic resin containing said resinous agent exhibits excellent mechanical strength, high anti-brasion and improved sliding properties.

Abstract: Silane-crosslinkable halogenated polymer composition and process of crosslinking the same.The silane-crosslinkable halogenated polymer composition contains a mixture including: 100 parts by weight of a halogenated polymer and about 0.1-20 parts by weight of an amino group-containing organic silane compound. The halogenated polymer composition silane-crosslinked is useful for the sheath and insulation of electric wires and cables and other moldings such as a hose.
