Polymers

摘要

The invention relates to polymers having a molecular weight (Mw) of from 5.5 x 10<3> to 10<5>, measured by gel permeation chromatography, which comprise, in the polymer chain, recurring structural units of the formulae I-IV in which R1 and R2, independently of one another, are each linear or branched C1-C6alkyl, unsubstituted or methyl-substituted C3-C6cycloalkyl, or phenyl or naphthyl which is unsubstituted or substituted by one or more halogen atoms or one or more C1-C4alkoxy, cyano or nitro groups, R3, R4, R5 and R6, independently of one another, are hydrogen or methyl, R7, R8, R9 and R10, independently of one another, are hydrogen, C1-C6alkyl, C1-C6alkoxy or halogen, w, x, y and z are a number greater than or equal to 1, and where the quotient Q, obtainable from the total number of structural units containing protecting groups divided by the total number of all structural units present, $is\; greater\; than\; 0.5\; and\; at\; most\; 0.9.\; These\; polymers\; are\; suitable\; for\; the\; production\; of\; printing\; plates,\; printed\; circuits\; and\; integrated\; circuits.$
