摘要：
A diyne-containing (co)polymer which is soluble in organic solvents, has excellent processability, and gives a cured coating film excellent in heat resistance, solvent resistance, low-dielectric characteristics, and mechanical strength; processes for producing the same; and a cured film.
The diyne-containing (co)polymer contains at least 10 mol% repeating units represented by the following formula (1) and has a weight-average molecular weight of from 500 to 1,000,000:
wherein Y represents a specific bivalent organic group; Ar represents a bivalent organic group; and n represents 0 or 1.
