Polu00cdmero unsaturated pre-filled etilenicamente; the process for preparation of polu00cdmero power; power polu00cdmero might be obtained by reau00c7u00e7o of at least one power polu00cdmero; composiu00c7u00e7o reticulu00c1vel resin; process of preparing a composiu00c7u00e7o reticulu00c1vel; utilizau00c7u00e7o of at least one power polu00cdmero; The process of utilizau00c7u00e7o a composiu00c7u00e7o; fine article obtained by reticulau00c7u00e7o of at least one composiu00c7u00e7o.The present invention relates to a pre polymer comprising unsaturated etilenicamente, at least one terminator x reagent by condensation, chosen from among the groups hidru00f3d and / or amine or isocyanate free, and eventually a terminator X 'etilu00eanica unsaturation.The prepolymer is the reaction product of the following components a and B: (a) a first component that comprises the following mixture: 1) at least one first resin, unsaturated hydroxy etilenicamente therefore terminations reagents and / or aminada specific, and / or (II) eventually, in P. Presence of at least one second resin different from the resin 1)Chosen among: the hidroxiladas etilenicamente unsaturated resins and / or the resin saturated hidroxiladas and / or aminadas, and / or (III) where at least a third resin saturated reagent; (IV) optionally, at least one monou00e1lcool up to 30% in equivalent of total OH + NH ~ 2 ~, and,(b) a second component B comprising at least one poliisocianato functionality equal to 2 or more than 2, a and B being in proportion to avoid gelation by crosslinking. The invention relates to a resin composition comprising at reticulu00e1vel, M. ENOS a pre polymer according to the invention, and their use in various fields of applications.
