Bis-phenol phosphates as clarifiers for polyolefin resins

摘要: Bis-phenol phosphates, are provided, represented by the formula: ##STR1## wherein: R is selected from group consisting of a carbon-to-carbon bond; thio sulfur --S--; and alkylidene ##STR2## in which 3 4 hydrogen, alkyl having one to about eighteen carbon atoms, cycloalkyl, including cycloalkylidene taken together as part cycloalkylene ring, three twelve atoms; 1 2 each cycloalkyl m 0 or 1; M metal atom can be monovalent polyvalent; n valence M, ranging four; useful improve clarity polyolefin resin compositions an amount within range 0.005 5 parts weight per 100 resin.
