Abstract
Provided is a poly(arylene ether ketone) resin which inhibits reactions such as molecular weight extension and crosslinking in a high-temperature molten state and which is excellent in melt viscosity stability and molding processability. The poly(arylene ether ketone) resin contains an alkylsulfonyl group represented by general formula (1). In the formula, R is an alkyl group containing one to four carbon atoms.
Claims17
A poly(arylene ether ketone) resin containing an alkylsulfonyl group represented by general formula (1) below:
- where R is an alkyl group containing one to four carbon atoms, and having a main chain structure represented by general formula (2) below:
- where X is represented by general formula (3-1) below and Y is represented by general formula (4-1 below:
- where n represents 0 to 2, and
- where m represents 0 to 3.
A method for producing a poly(arylene ether ketone) resin containing an alkylsulfonyl group represented by general formula (1) below, the method comprising either:
- (i) a reaction step of allowing a monomer represented by general formula (3-2) below and a monomer represented by general formula (4-2) below to react in the presence of a mixture of an organic sulfonic acid and phosphorus pentoxide or
- (ii) a reaction step of allowing a poly(arylene ether ketone) resin containing no alkylsulfonyl group to react in the presence of a mixture of an organic sulfonic acid and phosphorus pentoxide:
- where R is an alkyl group containing one to four carbon atoms,
- where n represents 0 to 2, and
- where m represents 0 to 3.
