    • The invention relates to a method of producing an article comprising an interpenetrating polymer network (IPN) and an article e.g. obtainable by the method. The method comprises i) providing an essentially transparent rubber substrate having a refractive index n 0 and being shaped to provide the desired shape of the article, and applying it in a reaction chamber, ii) providing a least one first monomer having a refractive index n 1 in homopolymerized condition wherein n 1 is lower than n 0 , iii) providing a least one second monomer having a refractive index n 2 in homopolymerized condition, wherein n 2 is higher than n 0 , iv) exposing said rubber substrate in said reaction chamber to said first and said second monomers to impregnate said rubber substrate with said monomers in the presence of an impregnation solvent comprising CO 2 under conditions wherein said CO 2 is in its liquid or supercritical state and v) co-polymerizing said first and said second monomers to form an IPN, wherein said at least one first monomer and said at least one second monomer are selected such that r 1 and r 2 independently of each other are 3 or less, where n = (Q 1 /Q 2 ) exp [-e1(e1 -e2)] and r 2 = (Q 2 /Q 1 ) exp [-e2 (e2-e1)] and Q 1 = denotes the intrinsic reactivity of the first monomer, Q 2 = denotes the intrinsic reactivity of the second monomer, and e1= denotes the polarity of the first monomer, and e2= denotes the polarity of the second monomer. The article comprises a body formed of a rubber substrate and an interpenetrating network of an interpenetrating copolymer and the article is essentially transparent.
