Embodiment 1

[0113] FR1: Add 160.2g of phenol, 112.2g of solid potassium hydroxide and 500ml of xylene to a 2L four-necked flask equipped with a Dimroth condenser, a Dean-Stark tube, a dropping funnel, a thermometer and a stirrer under nitrogen. The stream was heated to reflux at an oil bath temperature of 145°C. The produced water is removed from the system by azeotroping with xylene, and only xylene is returned to the system. Heating to reflux was carried out until distillation of the water produced ceased. The reaction takes 4 hours to complete.

[0114] The reaction vessel was immersed in an ice bath and cooled until the reaction mixture reached 10°C or lower, then 72.1 g of chlorophosphazene was deionized in 30 minutes using a dropping funnel while maintaining the reaction mixture at 10°C or lower. A mixed solution of the polymer (trimer: 95%, tetramer: 4%, other components: 1%) and 250 ml of xylene was added dropwise to the reaction mixture. After adding the mixed solution, the re...

[0116] FR2: Add 151.5g of phenol, 103.6g of solid potassium hydroxide and 500ml of xylene into a 2L four-necked flask equipped with a Dimroth condenser, a Dean-Stark tube, a dropping funnel, a thermometer and a stirrer and place under nitrogen The stream was heated to reflux at an oil bath temperature of 145°C. The produced water is removed from the system by azeotroping with xylene, and only xylene is returned to the system. Heating to reflux was carried out until distillation of the water produced ceased. The reaction takes 4 hours to complete.

[0117] The reaction vessel was immersed in an ice bath and cooled until the reaction mixture reached 10°C or lower, then 70.0 g of chlorophosphazene was deionized in 30 minutes using a dropping funnel while maintaining the reaction mixture at 10°C or lower. A mixed solution of the polymer and 250 ml of xylene was added dropwise to the reaction mixture. After adding the mixed solution, the reaction mixture was heated again and hea...

[0119] FR3: Add 158.0g of phenol, 110.0g of solid potassium hydroxide and 500ml of chlorobenzo into a 2L four-necked flask equipped with a Dean-Stark tube with a Dimroth condenser, dropping funnel, thermometer and stirrer and dissolve under nitrogen The stream was heated to reflux at an oil bath temperature of 145°C. The water produced is removed from the system by azeotroping with chlorobenzene, and only chlorobenzene is returned to the system. Heating to reflux was carried out until distillation of the water produced ceased. The reaction takes 6 hours to complete.

[0120] The reaction vessel was immersed in an ice bath and cooled until the reaction mixture reached 10°C or lower, then 72.1 g of chlorophosphazene was deionized in 30 minutes using a dropping funnel while maintaining the reaction mixture at 10°C or lower. A mixed solution of polymer and 250 ml of chlorobenzene was added dropwise to the reaction mixture. After adding the mixed solution, the reaction mixture w...

Abstract

A phosphazene composition whose volatile matter content at heating at 200ºC for 2 hr is in the range of 0.02 to 1.0 wt.%. This phosphazene composition is excellent in hydrolysis resistance and when added to a resin, can provide a resin composition that retains highly desirable balance among hydrolysis resistance, flame retardancy and electrical characteristic stability at high-frequency region of 1 GHz or over.

Description

technical field [0001] The present invention relates to a phosphazene composition having excellent hydrolysis resistance and a flame retardant and a flame retardant resin composition comprising the composition as an active ingredient. Background technique [0002] Since phosphazene compositions have excellent characteristics, they have been studied in various fields and they are applicable to a wide range of fields. For example, they are suggested for various applications such as polymer materials, rubber, lubricants, lithium-ion batteries, solar cells, fuel cells, non-flammable electrolytes, battery devices, anti-sticking agents, releasing films, rough surfaces Flame retardants for forming materials, waterproofing agents and fertilizers, pharmaceuticals such as anticancer drugs, AIDS inhibitors and dental materials. [0003] As for the flame retardant, conventional methods for flame retarding flammable resins include those involving adding chlorine compounds, bromine compo...
