Definitions
- the present invention relates to a novel phosphorus (P)-based oligomer, a polyester resin having excellent flame retardancy and a high degree of polymerization at the same time including structural units derived therefrom, a thermoplastic resin composition containing the polyester resin, and a molded article using the same. .
- Thermoplastic polyester resins have excellent chemical resistance, mechanical strength, heat resistance and electrical properties, and are widely used in housings and connectors of electronic/electrical and automotive parts.
- polyester resins have a property of burning well, in order to apply them to fields requiring flame retardancy, halogen-based flame retardants or antimony-based flame retardant aids have been added and used.
- halogen-based flame retardants or antimony-based flame retardant aids not only generate a large amount of toxic halogen gas in case of fire, but also have a problem in that an excessive amount of flame retardant must be used to achieve a desired flame retardant effect.
- a method of imparting flame retardancy to a polyester resin using a non-halogen flame retardant such as an organic phosphinate metal salt flame retardant, an organo phosphinate metal salt flame retardant, or melamine polyphosphate has been proposed.
- a non-halogen flame retardant such as an organic phosphinate metal salt flame retardant, an organo phosphinate metal salt flame retardant, or melamine polyphosphate.
- Patent Document 1 Korean Patent Registration No. 10-2285778
- the present invention has been made to solve the above problems, and provides a new polyester resin with improved flame retardancy and polymerization degree by synthesizing a new oligomer containing phosphorus (P) and polymerizing polyester using the same. to do as a technical task.
- thermoplastic resin composition containing the above-mentioned polyester resin and a molded article using the same.
- the present invention provides a phosphorus (P)-based oligomer represented by the following formula (1).
- a and A' are the same as or different from each other, and each independently represents a C 1 ⁇ C 40 alkylene group, a C 2 ⁇ C 40 alkenylene group, a C 2 ⁇ C 40 alkynylene group, a C 3 ⁇ C 40 A group consisting of a cycloalkylene group, a heteroalkylene group having 1 to 40 nuclear atoms, a heterocycloalkylene group having 3 to 40 nuclear atoms, a C 6 to C 60 arylene group, and a heteroarylene group having 5 to 60 nuclear atoms is selected from,
- the alkylene group, alkenylene group, alkynylene group, cycloalkylene group, heteroalkylene group, heterocycloalkylene group, arylene group and heteroarylene group of A and A' are each independently deuterium (D), halogen, cyano group , a nitro group, a C 1 ⁇ C 40 alkyl group, a C 6 ⁇ C 60 aryl group, and a heteroaryl group having 5 to 60 nuclear atoms. In the case of, they may be the same or different from each other,
- n is an integer from 1 to 10;
- n is an integer from 2 to 50;
- the phosphorus (P)-based oligomer represented by Chemical Formula 1 may have a weight average molecular weight (Mw) of 500 to 3,000 g/mol.
