3-16035/= Copolymers formed from N-hydroxyphenylmaleinimide (derivatives) and allyl compounds Abstract The invention relates to copolymers consisting of 30-100 mol%, relative to the total polymer, of structural units of the formulae I and II, the proportion of structural units of the formula I, relative to the proportion of I and II, being 5 to 95 mol%, Image (I), (II), in which R1 is C1-C4-alkyl, C1-C4-alkoxy or halogen, R2 is hydrogen or -COR3 and R3 is C1-C20-alkyl, m is 1, 2 or 3, n is 0, 1, 2, 3 or 4 and the sum of m and n is not more than 5, and A is selected from the group of radi- cals consisting of halogen, cyano or structural units of the formulae III to VIII Image (III), (IV), Image (V), (VI), (VII), (VIII), in which R4 and R6 independently of one another are hydroxyl,-O-?-R3 or glycidyl groups of the formula IXa or IXb Image (IXa), (IXb), R5 and R7 independently of one another are C1-C4-alkyl, C1-C4-alkoxy or halogen, o and q independently of one another are 0, 1, 2 or 3, p and r independently of one another are 0, 1,2,3, 4 or 5, it being necessary for the totals o+p and q+r to be not more than 5, R8 is hydrogen, C1-C20-alkyl, a glycidyl radical of formula IXa or a radical of formula VI, R9 is hydrogen, C1-C20-alkyl, cycloalkyl having 5-7 ring C atoms, phenyl, naphthyl or benzyl, R10 is hydrogen, C1-C20- or a glycidyl radical of the formula IXa, and the groups R11 and R12 independently of one another are hydrogen, C1-C20-alkyl, cycloalkyl having 5-7 ring C atoms, aryl or aralkyl which is substituted or unsubstituted or a glycidyl radical of the formula IXa, or, together with the common nitrogen atom, form a five-membered or six-membered, non- aromatic, heterocyclic ring, and R13 and R14 independently of one another are hydrogen or methyl, it being possible for the radicals R1 to R14 and A of a polymer molecule to be different, within the definitions given. The compounds are distinguished by high glass trans- ition temperatures and good flexibility and can be employed as binders in photoresist systems. The representatives con- taining glycidyl groups can also be used as self-crosslink- ing epoxide resins.
