Problems solved by technology

However, PEEK is still unsuitable as components exposed to ultra-high pressure and ultra-high speed environments due to relatively low heat resistance, and PAI and PI are limited in application as components due to low processability and productivity and high cost.

preparation example 1

[0247] Preparation example 1. Synthesis of phthalonitrile compound (PN1)

[0248] The compound (PN1) of the following chemical formula A1 was synthesized as follows.

[0249] 32.7 g of a compound of the following chemical formula A2 and 120 g of DMF (dimethylformamide) were introduced into a 3-neck round bottom flask, and stirred at room temperature to dissolve. Subsequently, 51.9 g of the compound of the following chemical formula A3 was added, and 50 g of DMF was added, followed by stirring to dissolve. Subsequently, 62.2 g of potassium carbonate was introduced together with 50 g of DMF, and the temperature was raised to 85° C. while stirring. After reacting for about 5 hours, the solution was cooled to room temperature.

[0250] The cooled reaction solution was poured into a 0.2N aqueous hydrochloric acid solution to neutralize and precipitate it, and after filtration, it was washed with water. Thereafter, the filtered reactant was dried in a vacuum oven at 100° C. for...

Description

technical field [0001] Cross References to Related Applications [0002] This application claims Korean Patent Application No. 10-2017-0061797 filed with KIPO on May 18, 2017 and Korean Patent Application No. 10-2018-0054368 filed with KIPO on May 11, 2018 rights and interests, the disclosure of which is incorporated herein by reference in its entirety. [0003] The present invention relates to a polymerizable composition having not only low friction characteristics but also excellent heat resistance, a prepolymer thereof, and an opposing friction component material using the same. Background technique [0004] In the automotive industry, many efforts are being made to reduce friction at energy transfer components (eg, power train, drive train, etc.) in order to reduce weight and improve energy efficiency. This is because only 15% of the energy of the fuel used in the car is transferred to the wheels, and 10% of this is lost due to friction of the drive components. [00...
