    Abstract: PROBLEM TO BE SOLVED: To obtain the α-crystal modification of a 2,2',2"-nitrilo(triethyltris(3,3',5,5'-tetra-tert-butyl-1,1'-biphenyl- 2,2'-diyl) phosphite) (NTTBP) by dissolving NTTBP in a short-chain ketone in heated condition, and cooling the solution. SOLUTION: This α-crystal modification of a 2,2',2"-nitrilo(triethyltris(3,3',5,5'- tetra-tert-butyl-1,1'-biphenyl-2,2'-diyl) phosphite) (NTTBP) of formula I is obtained by dissolving NTTBP in the formula of its melt, amorphous solid modification or β-crystal modification into a short-chain 3-7C ketone (e.g. acetone) in heated condition at 40-100 deg.C, and then cooling the solution to room temperature to crystallize the α-crystal modification of NTTBP.

    Abstract: PROBLEM TO BE SOLVED: To obtain the subject new additive mixture capable of remarkably reducing the release of the decomposition products of dibenzylidene sorbitol or its derivative, when its mixture of a polymer is processed, by adding an amide functional compound to the dibenzylidene sorbitol or its derivative. SOLUTION: This additive mixture comprises (A) dibenzylidene sorbitol or its derivative [preferably 1,3:2,4-di(benzylidene)-D-sorbitol, etc.,] and (B) an amide functional compound (preferably bisstearoyl ethylenediamine, bislauroyl ethylenediamine, etc.,) preferably in a B:A mixing ratio of 1.5:l to 1:1.5 as basic components. When added to a polymer, the objective mixture is preferably added so that the component B is contained in a concentration of 0.1-1wt.% based on the whole amount of the polymer. The polymer to be mixed with the objective mixture includes polyolefins.

    Abstract: PROBLEM TO BE SOLVED: To produce a 2,2',2"-nitrilo(triethytris(3,3',5,5'-tetra-tert-butyl-1,1'- biphenyl-2,2'-diyl) phosphite), which is used as a stabilizer for polymers, etc., by making a 6-chloro-tetratert-butylbenzo-dioxaphosphepine with triethanolamine and a tertiary amine react at specific mol ratios. SOLUTION: This 2,2',2"-nitrilo(triethyltris(3,3',5,5'-tetra-tert-butyl-1,1'- biphenyl-2,2'-diyl) phosphite), which is a highly effective stabilizer for polymers, is obtained by adding a 6-chloro-2,4,8,10-tetratert-butylbenzo[d, f][1,3,3]dioxaphosphepine (chlorophophite) of formula I into a solution of triethanolamine and a tertiary amine (e.g. triethylamine) at mol ratios of the chlorophosphite, tertiary amine and triethanolamine of (3.3-2.9):(3.3-2.9):1 to complete the reaction of them, and separating the product from the tertiary amine hydrochloride after the reaction.

    Abstract: By dividing the known condensation of acetoacetic acid diol esters with phenols into two process steps, a reduction in the cost of the entire process can be achieved. Methyl acetoacetate is first condensed with a phenol and the methyl 3,3-bis(4-hydroxyalkylphenyl)butanoate formed is reacted with the desired diol in the presence of a transesterification catalyst. In this way only one acetoacetic ester is necessary for various final products. The final products are useful stabilizers for plastics, in particular polyolefins.
