| abstract |
The invention relates to polymers with antimicrobial properties, consisting of: a) 99-40 wt % non functional vinylically polymerizable monomers and b) 1-60 wt % functional vinylically polymerizable monomers of general formula (I) wherein V = vinyl, (meth)acroyl, allyl or styryl, A = a possibly available linking unit, which can be alkyl, aryl, arylalkyl or hydroxy alkyl, which can also be interrupted by hetero atoms, e.g. by hetero atoms in urethane, carbonate, ester, amide or ether groups, wherein y = 0 or is 1, Hsp = a hydrophilic spacer of general formula (i) -(O-CH2-CH2)r- and/or (ii) -(O-CH2-CH(CH3))s with r = 0-40, s = 0-40 and r + s = 2-40, also m = 1.2 or 3 and R<1> = CH3, ethyl or benzyl, R<2> = an alkyl radical with 8-20 C-atoms, wherein t = 1, 2 or 3 and X <->= Cl <->, Br <->, I <-> or alkyl sulphate. |
