POLYIMIDE PRECURSOR, RESIN COMPOSITION, AND METHOD FOR PRODUCING RESIN FILM

摘要

Provided is a polyimide precursor comprising a structural unit L represented by formula (1) (in the formula, X1 represents a tetravalent group having 4-32 carbon atoms, each of R1, R2, and R3 independently represents a monovalent organic group having 1-20 carbon atoms, n represents 0 or 1, and each of a, b, and c is an integer of 0-4) and a structural unit M represented by formula (2) (in the formula, X2 represents a tetravalent group having 4-32 carbon atoms) such that 1/99 ≤ (number of moles of structural unit L/number of moles of structural unit M) ≤ 99/1 is satisfied.
