Claims
- 1. A moldable thermoplastic resinous composition comprising:
- (A) a beneficiated talc filler comprising a talc regarded, in the unbeneficiated states, as incompatible or unsuitable for use as a filler for thermoplastic resinous compositions, admixed with an effective amount of:
- (a) one or a mixture or octyl-or nonylphenyl/poly(ethylene oxide) condensates, and
- (b) one or a mixture of poly(ethylene glycols) or alkoxypoly(ethylene glycols); and
- (B) a moldable -hermoplastic resin.
- 2. A composition as recited in claim 1 in which said (a) is an octylphenol/poly(ethylene oxide) condensate.
- 3. A composition as recited in claim 1 in which said (b) is a poly(ethylene glycol).
- 4. A composition as recited in claim I in which said (a) is an octylphenol/poly(ethylene oxide) condensate having an average of 7-8 ethylene oxide units in its ether side chain and said (b) is a poly(ethylene glycol) having a molecular weight of from about 200 to about 300.
- 5. A composition as recited in claim 1 in which said talc is a montana talc and said octyl- or nonylphenol/poly(ethylene oxide) condensate and said poly(ethylene glycol) or alkoxypolyethylene glycol) are each present in an amount ranging from about 0.05% to about 4.0% by weight, with the total combined amount of said substances being no more than about 5.0% by weight, said weight percents being based on the weight of the unbeneficiated talc.
- 6. A composition as recited in claim 1 in which said talc is a Montana talc and said octyl--or nonylphenol/poly(ethylene oxide) condensate and said poly(ethylene glycol) or alkoxypoly(ethylene glycol) are each present in an amount ranging from about 0.2% to about 1.5% by weight, with the total combined amount of said substances being no more than about 3.0% by weight, said weight percents being based on the weight of the unbeneficiated talc.
- 7. A composition as recited in claim 1 in which the thermoplastic resin is a polyolefin.
- 8. A composition as recited in claim 7 in which the polyolefin is polypropylene.
- 9. A composition as recited in claim 8 which also contains a heat stabilizer.
- 10. A molded article comprising a composition as recited in any one of claims 1-9, inclusive.
