Stabiliser, comprising the reaction product of at least one macromer with at least one C4-30-alkyl(meth)acrylate in at least one polyether polyol 1 in the presence of at least one free radical polymerisation catalyst and optionally at least one chain transfer agent, the at least one macromer being at least one molecule which comprises in its structure one or more polymerisable double bonds, able to copolymerise with C4-30-alkyl(meth)acrylates and which furthermore comprises in its structure one or more hydroxyl-terminated polyether chains. Un estabilizante que comprende el producto de reacción de al menos un macrómero con al menos un (met)acrilato de alquilo C4-30 en al menos un poliol poliéter 1, en presencia de al menos un catalizador de polimerización por radicales libres y, opcionalmente, al menos un agente de transferencia de cadena, al menos un macrómero que es al menos una molécula que comprende en su estructura uno o más enlaces dobles polimerizables, capaces de copolimerizarse con (met)acrilato de alquilo C4-30 y que además comprende en su estructura una o más cadenas de poliéter terminadas en hidroxilo.
