Disclosed herein is a novel fire-retardant polyolefin composition comprising a polyolefin, an organohalogenous fire retardant and a carbonic acid ester represented by the formula (I): ##STR1## wherein R and R' respectively represent an alkyl group, an alkenyl group, an alkynyl group, a cycloalkyl group, an aralkyl group or an aryl group, Z represents a residual group of an aliphatic diol, an alicyclic diol, an aromatic diol, a diphenyl ketone diol, or a diphenylsulfone diol and n is 0 or 1.

Fire-retardant polyolefin composition

A novel process for producing D-2-amino-2-(1,4-cyclohexadienyl)-acetic acid useful as an intermediate compound for producing 6-aminopenicillanic acid or 7-aminocephalosporanic acid is disclosed.

Process for producing D-2-amino-2-(1,4-cyclohexadienyl)acetic acid

Disclosed is a pre-copolymer containing diallyl phthalate units and triallyl isocyanurate units.

Pre-copolymer comprising diallyl phthalate and triallyl isocyanurate

A process for producing tri(allyl isocyanurate) by reacting an alkali cyanate and an allyl halide in an aprotic polar solvent, which comprises distilling off the solvent after the completion of the reaction, adding water or an aqueous solution of hydrogen chloride to a reaction mixture containing tri(allyl isocyanurate), forming a tri(allyl isocyanurate) layer and an aqueous layer and then separating the tri(allyl isocyanurate) layer from the aqueous layer.

Process for producing triallyl isocyanurate

An adhesive composition comprises (a) a resinous composition produced by mixing an aromatic primary amine with an aqueous solution or emulsion containing a polymer or copolymer of acrylamide and (b) formaldehyde or a derivative thereof as main components.
