    Abstract: Sol gel process for producing protective films for polymeric substrates Sol gel process for producing protective filmsfor polymeric substrates, the process relates to the sol gel reaction of a metal or semi-metal alkoxide carried out in certain conditions. The sols obtained were, without limiting, spin- or dip-coated onto polymeric substrates then thermally cured into transparent- abrasion resistant coating.Such coating transmit visible light, but absorb wavelengths of ultraviolet light which cause degradation of the substrate surface and resultant adhesion-loss of the protective coating upon weathering.
