BIS-PHENOL PHOSPHATES AS CLARIFIERS FOR POLYOLEFIN RESINS

摘要

Bis-phenol phosphates, are provided, represented by the formula: I wherein: R is selected from the group consisting of a carbon-to-carbon bond; thio sulfur -S-; and alkylidene in which R3 and R4 are selected from the group consisting of hydrogen, alkyl having from one to about eighteen carbon atoms, and cycloalkyl, including cycloalkylidene in which R3 and R4 are taken together as part of a cycloalkylene ring, having from three to about twelve carbon atoms; R1 and R2 are each selected from the group consisting of hydrogen, alkyl having from one to about eighteen carbon atoms; and cycloalkyl having from three to about twelve carbon atoms; m is 0 or 1; M is a metal atom which can be monovalent or polyvalent; and n is the valence of the metal atom M, ranging from one to about four; useful to improve clarity of polyolefin resin compositions in an amount within the range from 0.005 to 5 parts by weight per 100 parts of resin.
