Abstract:
A coated polymer article wherein the coating is covalently bound to the polymer surface via double bonds of the polymer, comprising a) P comprises a basic polymer and further groups â€”Lâ€”CH(â€”X(R1)p)â€”CH2(â€”Y(R2)p); b) L is a part of a pending group i) projecting from the basic polymer and ii) comprising a double bond that has been utilized for introducing â€”X(R1)p and â€”Y(R2)p; c) X and Y are independently selected from halogens, in particular Br, and N, S and O; d) R1 is hydrogen, a straight, branched or cyclic alkyl or acyl group, such as C1-C10 alkyl, C1-C18 acyl, or R2 when X is N, O or S with particular emphasis for X equals Y equals O; e) R2 is hydrogen, straight, branched or cyclic alkyl such as C1-C18 alkyl, â€”R3(â€”NH2)q, alkylaryl or arylalkyl in which the alkyl part may contain 1-18 carbon atoms, â€”R3(â€”NHâ€”CR4&boxH;O)q, â€”CR4&boxH;O or poly lower alkyloxy groups that may have been terminally acylated or alkylated; f) p is an integer 0-3, with the provision that when X is halogen p equals O, when X is O p equals 1, when X is S p equals 1 or 2, and when X is N p equals 1, 2 or 3, and with the further provision that for p equals 2 or 3 the two or three groups R2 may be identical or different; g) R3 is a straight, cyclic or branched alkyl, â€”O-alkyl, hydroxyalkyl, phenylalkyl, with up to 18 carbon atoms in the alkyl part, and R4 is a straight, branched or cyclic alkyl group, such as C1-C18 alkyl; h) q is an integer >0 representing that one or more hydrogens in R3 may have been replaced with a respective primary amino group (â€”NH2) or a respective â€”NHâ€”CR4&boxH;O group.
