Described herein are novel metal salts capable as nucleating agents for polyolefins. The present invention relates to such salts synthesized by reacting potassium hydroxide with carboxylic acids and further, to the achievement of high crystallization temperatures in polypropylene compositions upon dispersal therein of formulations containing one or more of the said metal salts.
The invention provides a thermoplastic polymer composition comprising a polyolefin polymer and a nucleating agent. The nucleating agent comprises a compound conforming to the structure of Formula (I)
The invention also provides a series of compounds encompassed by the structure of Formula (I).
A nucleating agent containing a phosphoric acid aromatic ester metal salt represented by formula (I) and having an average major-axis length of 10 µm or less, an average aspect ratio of 10 or less, and a bulk specific gravity of 0.1 or more:
(wherein R1 represents C4-C8 alkyl group, R2 represents hydrogen or C1-C8 alkyl group, R3 represents C1-C4 alkylidene group, A is a metal having a valence of n, and n is an integer of 1 or 2). The nucleating agent exhibits excellent handling property when incorporated into a resin, and is highly effective in improving transparency and mechanical strength of the resin containing the agent.

According to this invention, an amorphous or pseudo-boehmite-type hydrated alumina gel and an alkali metal carbonate or bicarbonate as starting materials are reacted in an aqueous medium to give a method of producing a process for producing an alkali aluminum complex hydroxide carbonate salt which is industrially low-cost and has high productivity. Furthermore, by using a gibbsite-type hydrated alumina, a lithium aluminum complex hydroxide carbonate salt can be synthesized by a migration method.
The lithium aluminum complex hydroxide carbonate salt and the sodium aluminum complex hydroxide carbonate salt obtained by the processes of the present invention have excellent compoundability in pigments and resins.
In addition, these complex salts have no foaming hazards at the time of processing the resins and are useful as resin fillers for halogen capturing property, infrared ray absorbing property and excellent transparency. They are especially useful as a stabilizer (halogen capturing agent) for resin films, a warmth-keeping agent (infrared absorbing agent) and an anti-blocking agent.
