Abstract:
Reactive side-chain polymers within the class of polyimides, polyamic acids and esters thereof, characterized in that they comprise monovalent side chains of the general formula I:--L.sub.1 --D--L.sub.2 --C.sub.f Iwherein the monovalent link is to a polymer main chain and wherein:L.sub.1 and L.sub.2 each, independently, is a covalent bond or a linking group selected from the group of --O--, --S--, --NR.sub.1 --, --O--CO--, --CO--O--, --NR.sub.1 --CO--, --CO--NR.sub.1 --, --NR.sub.1 --CO--O--, --O--CO--NR.sub.1 --, --NR.sub.1 --CO--NR.sub.1 --, and straight-chain and branched-chain alkylenes represented by --(CH.sub.2).sub.n --, --L.sub.3 --(CH.sub.2).sub.n --,--(CH.sub.2).sub.n --L.sub.3, --L.sub.3 --(CH.sub.2).sub.n --L.sub.4 --, each optionally mono- or poly-substituted by fluorine or chlorine and optionally chain interrupted by --O-- or --NR.sub.1, wherein L.sub.3 and L.sub.4 are selected from the group of--O--, --S--, --NR.sub.1 --, --O--CO--, --CO--O--, --NR.sub.1 --CO--, --CO--NR.sub.1 --, --NR.sub.1 --CO--O--, --O--CO--NR.sub.1 --, --NR.sub.1 --CO--NR.sub.1 --, R.sub.1 is a hydrogen or lower alkyl group and n is 1 to 20;D is a divalent group containing 1 to 4 carbon--carbon double bonds, selected from the group of C.sub.3 -C.sub.24 aliphatic, C.sub.3 -C.sub.24 alicyclic, C.sub.8 -C.sub.24 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 .PI.-system within the side-chain;C.sub.f represents a monovalent C.sub.4 to C.sub.20 fluorocarbon radical.
