Polyarylate resin, production method thereof and polyarylate resin composition |
| abstract |
The objective of the present invention is to provide a polyarylate resin which is excellent in flow properties and reactivity with an epoxy resin and can form a cured material sufficiently excellent in heat-resisting properties and dielectric properties, and a production method thereof. The present invention provides a polyarylate resin comprising a dihydric phenol component and an aromatic dicarboxylic acid component and having a hydroxyl group concentration of 100geq/ton or more. The present invention also provides a production method of the polyarylate resin comprising, carrying out an acetylation reaction and an acetic acid-elimination polymerization reaction, wherein a hydroxyl carboxylic acid component is added after the acetylation reaction and before the acetic acid-elimination polymerization reaction. |
