ONE-SHOT PRODUCTION OF OPTICALLY CLEAR, LIGHT STABLE URETHANE-UREA ELASTOMERS AND A ELASTOMER, AS A EXAMPLE OF THIS METHOD

摘要

the invention is an optically clear, for the production of polyurethane fu00e9nyu00e1llu00f3 karbamidelasztomerek refers to the initial softening, which pontjalegalu00e1bb 130 degrees celsius.according to the invention can be applied, for example, produced elasztomereku00fcveghelyettesu00edtu0151ku00e9nt, ju00e1rmu0171vekbennapfu00e9nytetu0151ku00e9nt, front, rear and oldalablakku00e9nt and elu0151nyu00f6senalkalmazhatu00f3ak optical applications, such as, mintszemu00fcveglencsu00e9k or safety glasses.the invention is a liquid szerintielju00e1ru00e1s reagu00e1ltatnak) during the poliizocianu00e1tot could vagypoliizocianu00e1t of 5 to 50% by weight of nco group, 2 - 3 at a temperature of 25 degrees celsius, average funkcionalitu00e1su00fa, less than 5000mpas viscosity, and (b) an isocyanate reactive component. 1), aromatic amine group containing that compound2) a hydroxyl compound, and (c) an organo metallic csoportottartalmazu00f3 contains katalizu00e1torjelenlu00e9tu00e9ben, at room temperature, the components are processed and 95 to 120 isocyanate index value on the szerszu00e1mba. the elju00e1ru00e1segylu00e9pu00e9ses. the invention further relates to the elju00e1ru00e1ssalelu0151u00e1llu00edthatu00f3 forms an optically clear, fu00e9nyu00e1llu00f3 polyurethane karbamidelasztomer. oh
