Abstract:
Reactive side-chain polymers within the class of polyimides, polyamic acids and esters thereof, comprising identical or different repeat units selected from one or more of the formula wherein L2 is a covalent bond or a linking group selected from the group of â€”Oâ€”, â€”Sâ€”, â€”NR1â€”, â€”Oâ€”COâ€”, â€”COâ€”Oâ€”, â€”NR1â€”COâ€”, â€”COâ€”NR1â€”, â€”NR1â€”COâ€”Oâ€”, â€”Oâ€”COâ€”NR1â€”, and straight-chain and branched-chain alkylenes represented by â€”(CH2)nâ€”, â€”L3â€”(CH2)nâ€”, â€”(CH2)nâ€”L3, â€”L3â€”(CH2)nâ€”L4â€”, each optionally mono- or poly-substituted by fluorine or chlorine and optionally chain interrupted by â€”Oâ€” or â€”NR1, wherein L3 and L4 are selected from the group of â€”Oâ€”, â€”Sâ€”, â€”NR1â€”, â€”Oâ€”COâ€”, â€”COâ€”Oâ€”, â€”NR1â€”COâ€”, â€”COâ€”NR1â€”, â€”NR1â€”COâ€”Oâ€”, â€”Oâ€”COâ€”NR1â€”, R1 is selected from the group of H and lower alkyl group and n is 1 to 20;L1 is selected from the group of L2, â€”NR2â€”, â€”NR2â€”COâ€”, â€”COâ€”NR2â€”, â€”NR2â€”COâ€”Oâ€”, â€”Oâ€”COâ€”NR2â€”, wherein R2 is selected from the group of H, lower alkyl group, and â€”Dâ€”L2â€”Cf; D is a divalent group containing 1 to 4 carbon-carbon double bonds, selected from the group of C3-C24 aliphatic, C3-C24 alicyclic, C8-C24 arylalkyl groups, all optionally substituted with 1 to 4 heteroatoms selected from the group of oxygen, nitrogen and sulfur and optionally mono- or poly-substituted by fluorine, chlorine or cyano, wherein the carbon-carbon double bond(s) are isolated from any other Î -system within the side-chain; Cf represents a monovalent C4 to C20 fluorocarbon radical; A is a trivalent unsubstituted or optionally fluoro-, chloro-, cyano-, alkyl-, alkoxy-, fluoroalkyl- or fluoroalkoxy-substituted aromatic or alicyclic group; B is hydrogen or a monovalent organic group derived from an alcohol after formal removal of the hydroxyl group; and M is selected from the group of wherein Z is independently selected from the group of a covalent bond, â€”Oâ€”, â€”Sâ€”, â€”NR1â€”, straight-chain and branched-chain alkylenes represented by â€”(CH2)nâ€”, â€”L5â€”(CH2)nâ€”, â€”(CH2)nâ€”L5, â€”L5(CH2)nâ€”L6â€”, each optionally mono- or poly-substituted by fluorine or chlorine and optionally chain interrupted by â€”Oâ€” or â€”NR1, wherein L5 and L6 are selected, independently, from the group of â€”Oâ€”, â€”Sâ€”, â€”NR1â€”, â€”Oâ€”COâ€”, and â€”COâ€”Oâ€”; and m is 1 or 0.
