Abstract

To present a thermoplastic resin composition that gives a molded product with a surface to which dust is less likely to adhere. This patent presents a method of improving the appearance of the surface of a thermoplastic molded product.

Claims (13)

1. Thermoplastic resin composition comprising 0.0001 to about 0.05% by weight of halogenated carbon sulfonate of a polysubstituted phosphonium compound per 100% by weight of a thermoplastic resin comprising an aromatic polycarbonate prepared by the fusion method.

2. Thermoplastic resin composition comprising 0.0001 to about 0.001% by weight of halogenated carbon sulfonate of polysubstituted phosphonium compound per 100% by weight of a thermoplastic resin comprising an aromatic polycarbonate prepared by the fusion method.

3. Thermoplastic resin composition of claim 1 , wherein the halogenated carbon sulfonate of polysubstituted phosphonium compound is sulfonic acid phosphonium compound represented by the following formula (1):

wherein, X represents any one selected from a group of halogen and hydrogen, where X may or may not be the same, with the proviso that at least one of X is halogen, n, m and p varies from 0 to 12, Y is either absent or it is selected from a group consisting of heterocyclic group, nitrogen, oxygen, sulfur, selenium, phosphorous and arsenic, R 1 , R 2 and R 3 may be the same or different, and are selected from aliphatic hydrocarbon having 1 to 8 carbon atoms and aromatic hydrocarbon with 6 to 12 carbon atoms and R 4 represents a hydrocarbon group with 1 to 18 carbon atoms.

4. Thermoplastic resin composition of claim 3 , wherein X is fluorine.

5. Thermoplastic resin composition of claim 3 , wherein n is 3 and R 1 , R 2 and R 3 are individually alkyl groups with 4 carbon atoms, Y is absent and m and p are 0.

6. Thermoplastic resin composition comprising 0.0001 to about 0.03% by weight of halogenated carbon sulfonate of a polysubstituted phosphonium compound per 100% by weight of a thermoplastic resin comprising an aromatic polycarbonate prepared by the fusion method.

7. Method for improving fern marks of a molded product by adding 0.0001 to about 0.05% by weight of a halogenated carbon sulfonate of a polysubstituted phosphonium compound to 100% by weight of a thermoplastic resin comprising an aromatic polycarbonate prepared by the fusion method.

8. Method for improving fern marks of a molded product by adding 0.0001 to about 0.001% by weight of a halogenated carbon sulfonate of a polysubstituted phosphonium compound to 100% by weight of thermoplastic resin comprising an aromatic polycarbonate prepared by the fusion method.

9. Method for improving fern marks of a molded product of claim 7 , wherein the halogenated alkyl sulfonate of a polysubstituted phosphonium compound is a sulfonic acid phosphonium compound represented by the following formula (1):

wherein, X is selected from a group of halogen and hydrogen where X may or may not be the same, with the proviso that at least one of X is halogen, n, m and p have the values between 0 and 12, Y is either absent or it selected from a group consisting of heterocyclic group, nitrogen, oxygen, sulfur, selenium, phosphorous and arsenic, R 1 , R 2 and R 3 may be the same or different, and are selected from aliphatic hydrocarbon with 1 to 8 carbon atoms and aromatic hydrocarbon with 6 to 12 carbon atoms and R 4 represents hydrocarbon with 1 to 18 carbon atoms.

10. Method for improving fern marks of a molded product of claim 9 , wherein X is fluorine.

11. Method for of improving fern marks of a molded product of claim 9 , wherein n is 3 and R 1 , R 2 and R 3 and R 4 are alkyl groups with 4 carbon atoms respectively, Y is absent and m and p are 0.
