Abstract: New bis-[4-(m,m'-di-tert.-butyl-p-hydroxyphenyl)-butyl-(2)] dicarboxylic acid esters which are starting materials for the manufacture of dyes, pesticides and additives for plastics, especially stabilizers for polyolefins and polyamides, and are themselves stabilizers, aging retardants or antioxidants for organic products.

Abstract: Master batches for talcum-contg. moulding compsns. contain, by wt., 100 pts. talcum, 20-100 pts. monoolefin polymer, and also stabiliser compsn. contg. (i) 0.1-20 pts. phenolic antioxidant, (I), (ii) 0.1-30 pts. thioacid ester (II) (iii) 0.1-30 pts. B cpds. (III). The stabiliser compsn. improves the heat-stability of the moulding compsns. and allows prodn. of injection-moulded talcum-contg. propylene polymer articles. In an example, master batches for adding to polypropylene contained talcum, polypropylene, tri-(3,5-di-tert.-butyl-4-hydroxybenzyl)-isocyanurate, dilauryl thio-dipropionate and Zn borate.
