Definitions
- the present invention relates to a fluororubber copolymer and a composition for curing the same, and more particularly, to a fluororubber copolymer having improved low-temperature sealability while maintaining the excellent performance of a conventional fluororubber, and a copolymer thereof.
- the present invention relates to a curing composition comprising a coalescence.
- Fluorororubber mainly vinylidene fluoride (VdF) units, has excellent heat resistance, chemical resistance, solvent resistance, fuel oil resistance, etc., and is used in the automotive industry, semiconductor industry, chemical industry, etc.
- VdF vinylidene fluoride
- O-rings In the field of O-rings, they are widely used in the form of O-rings, hoses, stem seals, shaft seals, diaphragms, etc.
- conventionally used fluororubber is inferior to other rubber materials in cold resistance.
- Cold resistance is usually evaluated by the glass transition temperature in the case of unvulcanized copolymers, and in the case of molded products, it is usually determined by the Gehman torsion test, TR test (ASTM D1329), low-temperature embrittlement test, etc. It is evaluated, but when it is used as a sealing material such as O-ring, the difficulty of liquid leakage at low temperature, that is, the low temperature compression set of the material is directly an important index.

If the proportion of VdF units is less than 40 mol%, the glass transition temperature of the copolymer will increase, and the cold resistance will deteriorate. If the proportion of the VdF unit exceeds 90 mol%, the rubber elasticity is significantly reduced because the amorphous nature of the copolymer is impaired.

- the proportion of the HFP unit is less than 3 mol%, the VdF unit tends to crystallize, and it is necessary to add the PMVE unit, and as a result, the production cost tends to increase. If it is less than 25 mol%, the cold resistance deteriorates.
- the proportion of the TFE unit is less than 3 mol%, the VdF unit tends to crystallize, and it is necessary to add a PMVE unit, and as a result, the production cost tends to increase. If it exceeds 40 mol%, the cold resistance deteriorates.

- the amount of the diiodine compound present in the copolymer is determined by its molecular weight because it functions as a chain transfer agent as described in JP-A-53-12591.
- the iodine introduced into the polymer also functions as a bridge point. Therefore, when the amount of iodine introduced into the copolymer by the diiodine compound represented by the general formula (1) is less than 0.01% by weight based on the total weight of the copolymer, the molecular weight of the polymer is large. If it is too hard, the fluidity during the vulcanization reaction is impaired, and the crosslink density is lowered, so that the molded article cannot exhibit sufficient breaking strength. On the other hand, if the content exceeds 1% by weight, the molecular weight becomes too low, which hinders the rubber kneading operation.
