Abstract
The present invention is directed to a radically curable chemical composition in form of a resin for the production of materials having an intrinsic antimicrobial effect, to the applications of these materials, to a method for the preparation of these resins and materials, and to the use of an amino-functionalized styrene derivative as a reactive diluent. The cross-linked plastic materials formed after curing have an intrinsic antimicrobial effect without the use of additional biocides.
Claims10
A resin composition for the preparation of products having an antimicrobial effect, containing
- a) vinyl ester and/or vinyl ester urethane, and
- b) styrene derivative as a reactive diluent,
- wherein for each double bond in component a) there are 0.5 to 8 styrene derivative molecules present in the composition,
- wherein component b) is amino-functionalized and the amino functionality is of the formula
- —(CH2)q—NHpR1R2Ap,
- wherein
- q is either 1 or 2,
- p is 0 or 1,
- R1 is selected from H, linear or branched or cyclic alkyl radicals comprising 1 to 10 carbon atoms,
- R2 is a linear or branched or cyclic alkyl radical comprising 1 to 10 carbon atoms,
- A is the anion of an acid, and
- the amine nitrogen N of the above formula is neutrally (p=0) or positively (p=1) charged,
- wherein the amino-functionalized styrene derivative is selected from the group consisting of
- and mixtures thereof,
- wherein R1 is hydrogen and
- R2 is selected from the group consisting of isopropyl, tert-butyl and tert-pentyl.
