Abstract: A ceramic-making composition comprising at least one starting powder selected from the group consisting of powders of metals, powders of metal oxides, powders of metal carbides, powders of metal nitrides and powders of metal borides, and a synthetic resin binder. To enhance plastic moldability such as injection moldability and extrusion moldability and facilitate dewaxing, a polyalkylene carbonate is used as the synthetic resin binder.

Abstract: A fire-retardant 1-butene resin composition composed of(A) 100 parts by weight of a 1-butene polymer or copolymer containing 0 to 20 mole % of an olefin with 2 to 20 carbon atoms other than 1-butene as a comonomer,(B) 110 to 1,000 parts by weight of an inorganic hydroxide selected from the group consisting of magnesium hydroxide and aluminum hydroxide, and(C) 10 to 150 parts by weight of a graft-modified olefin resin resulting from grafting of an unsaturated carboxylic acid or its functional derivative to a polymer or a copolymer of an olefin having 3 to 8 carbon atoms or a copolymer of said olefin with up to 30 mole % of ethylene.

Abstract: A resin composition comprising a poly-1-butene polymer and at least one hindered phenol selected from the group consisting of (a) 3,5-di-tert-butyl-4-hydroxybenzoates of the following formula ##STR1## wherein R represents an alkyl group having 1 to 18 carbon atoms or an aryl group having 6 to 18 carbon atoms, (b) 1,3,5-trimethyl-2,4,6-tris(3,5-di-tert-butyl-4-hydroxybenzyl)benzene, (c) 1,3,5-tris(4-tert-butyl-3-hydroxy-2,6-dimethylbenzyl)isocyanurate, (d) tris(3,5-di-tert-butyl-4-hydroxybenzyl)isocyanurate, (e) n-octadecyl-3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate, (f) a nickel salt of a monoethyl ester of bis(3,5-di-tert-butyl-4-hydroxybenzylphosphonic acid), (g) 2,2'-dihydroxy-3,3'-di(.alpha.
