| titleOfInvention | Method for the production of cross-linkable acrylate contact adhesive materials |
| abstract | The invention relates to a method for the production of cross-linked acrylate contact adhesive materials characterised in that polyacrylates are firstly produced from the following monomers by free-radical (co-)polymerisation: (d) acrylic and methacrylic acid monomers with the following structure, where R1 = H or CH3 and R2 = an alkyl chain with 2 - 20 C atoms, at a proportion of 45 99.5 wt. % of the monomer mixture, (e) one or several carboxylic acid anhydrides, containing olefinic double bonds, at a proportion of 0.5 - 25 wt. % of the monomer mixture, (f) further unsaturated olefinic monomers containing functional group A, at a proportion of 0 - 30 wt. % of the monomer mixture. The polymers thus produced are concentrated to give a polyacrylate material with a solvent content ≤ 2 wt. %, further monomers are added to the polyacrylate material, which contain at least two functional groups B and C, whereby the group B can undergo polymerisation-type reactions with the carboxylic acid anhydrides and the groups C are cross-linkable groups. A reaction between the functional groups B and the carboxylic acid anhydrides occurs, which links the monomer containing the functional group B to the polymer in the form of a sidechain. After the reaction between the functional group B and the carboxylic acid anhydride a cross-linking of the polymers is carried out by means of an energetic irradiation. |
