A liquid crystal compound of the present invention is represented by the following general Formula I: ##STR1## wherein R.sub.1 and R.sub.2 are independently a linear or branched alkyl group or alkoxy group having 1 to 14 carbon atoms, provided that at least one of R.sub.1 and R.sub.2 is an alkyl group; --Y-- is a group represented by the following Formula (II) or (III); and X.sub.1, X.sub.2, X.sub.3, and X.sub.4 are independently a hydrogen atom or a fluorine atom: ##STR2##
A vinyl chloride resin composition that has better electrical insulating properties than existing vinyl chloride resin compositions and a wire coating material that includes the vinyl chloride resin composition are provided.
A vinyl chloride resin composition contains 0.1 to 3 parts by weight of synthetic aluminum silicate per 100 parts by weight of a vinyl chloride resin, the synthetic aluminum silicate having an apparent specific gravity of 7 ml/g or more. Synthetic aluminum silicate having a specific surface area of 400 m2/g or more can be preferably used. The wire coating material contains the vinyl chloride resin composition.
A waterproof sheet comprising a vinyl chloride-based resin composition which comprises 100 parts by weight of a vinyl chloride-based resin (A), 5 to 100 parts by weight of a plasticizer (B), 0.05 to 5 parts by weight of a hindered amine compound (C) represented by the following general formula (I), and 0.05 to 5 parts by weight of a benzotriazole-based ultraviolet light absorber (D) represented by the general formula (II):
wherein R1 and R2 represent each independently an alkyl group having 4 to 20 carbon atoms or a cycloalkyl group having 5 to 6 carbon atoms;
wherein R3 represents an alkyl group having 1 to 12 carbon atoms.
The invention relates to a flame-retardant chlorine-containing resin composition obtained by blending the following component (A), component (B), and component (C), and additionally component (D) if necessary, into a chlorine-containing resin: Component (A): a (poly)phosphate compound represented by the following general formula (1); Component (B): a (poly)phosphate compound represented by the following general formula (3); Component (C): wood flour; and Component (D): zinc oxide. In the formula (1), n represents a number from 1 to 100; X1 represents e.g. a triazine derivative represented by the general formula (2); and 0 < p ≤ n+2. In the formula (2), Z1 and Z2 each represent e.g. a -NR5R6 group. In the formula (3), r represents a number from 1 to 100; Y1 represents e.g. [R1R2N(CH2)mNR3R4]; R1, R2, R3, and R4 each represent e.g. a linear or branched alkyl group having 1 to 5 carbon atoms; m represents an integer from 1 to 10; and 0 < q ≤ r+2.
