Ethylene copolymer with comonomer units containing photochemically-activatable groups, used for the production of separating membranes, chromato-graphic stationary phases, lacquer, printing ink and toners

摘要

Ethylene copolymers (ECP) with at least one comonomer unit containing a photochemically-activatable group (PAG). Independent claims are also included for (1) a method (M1) for the production of ECP by polymerisation of (a) ethylene with (b) comonomer(s) containing PAG and (c) unsaturated carboxylic acid(s) or ester(s) at 170-300[deg]C and 500-4000 bar (2) a method (M2) for the production of ECP by polymerising (a) with (c) as above and then reacting the polymer with a compound of formula H-(X)n-(A)m-P* (IV) (3) materials (MECP) made from ECP for separating substances (4) a method (M3) for the production of MECP by exposing ECP to actinic radiation (5) a method (M4) for separating substances using MECP (6) a method (M4) for the production of lacquers, printing ink and toners by using ECP (7) micronised ECP with a number-average particle diameter of not more than 30 microns (8) lacquers, printing ink and toners containing or made from ECP (9) a method (M5) for printing substrates using such lacquers, ink and toners (10) printed substrates obtained by M5 .
