<p>Composition based on (meth)acrylate, comprises polyhedral oligomeric silicon-oxygen clusters (I) (0.01-15 wt.%). Composition based on (meth)acrylate, comprises polyhedral oligomeric silicon-oxygen clusters of formula ((R aA bX iSiO 1.5) m(R cA dX jSiO) n(R eA fX kSi 2O 2.5) o(R gA hX lSi 2O 2) p)) (I) (0.01-15 wt.%). Either a, b, c, d, i : 0-1; f, h : 0-2; j : 1-2; and k : 0-3; or b+d+f+h : >= 1; i+j+k+l : >= 1; m+n+o+p : >= 4; a+b+i : 1; c+d : j = 2; e+f+k : 3; and g+h+l : 4; R : H, alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, cycloalkynyl, aryl or polymer unit (all are optionally substituted) or functionalized polyhedral oligomeric silicon-oxygen cluster units, which are bonded through a polymer unit or a bridging unit; X : at least one monomer building block with at least one double bond (optionally substituted with R) or optionally oxy, OH, alkoxy, carboxy, silyl, silyloxy, halo, epoxy, ester, fluoroalkyl, isocyanate, acrylate, methacrylate, mercapto, nitrile, amino or phosphine (all are optionally substituted with R); A : hydrophobic substituent comprising fluorinated hydrocarbon, preferably fluoro alkyl trialkoxysilane of formula (CF 3((CF 2) o(CH 2) p)Si(OR) 3; and o, p : 0-12.</p> |
