Abstract: The invention provides a composition of matter, which is suitable for manufacturing candles by pressing/extruding, which is based on stearic/palmitic acid and also comprises:0.2-10% (w.w) of a crystal modifier and optionally 0.5-15% (w.w) of another, as to carbon chain length adjacent, natural fatty acid and/or such fatty acid derivative. Preferably the stearic/palmitic acid is a mixture of stearic acid and palmitic acid in the weight range of 20-80:80-20.The crystal modifier is usually of the ester type and is derived from a polyol with 2-4 hydroxyl groups and higher fatty acid and/or dimeric fatty acid.

Abstract: By the incorporation of small amounts of specific polyamides into polyalkenes, such as polypropylene and polyethylene, it is possible to significantly improve the dyeing properties, including color intensity, color homogeneity and color fastness, of the polyalkene. Polyamides useful for this purpose are derived from mixed dicarboxylic acids, diamine and triamine containing two primary and one tertiary amine groups.
