Polymer polyols and dispersions are prepared by polymerizing certain starting materials in a continuous phase. The continuous phase includes a polyol containing hydroxylmethyl groups, which is derived from a fatty acid. The dispersed phase may be, for example, a vinyl polymer, a polyurea or a polyurethane-urea.
On prépare des polyols polymères et des dispersions de polymères par polymérisation de certaines matières de départ dans une phase continue. La phase continue comprend un polyol contenant des groupes hydroxylméthyle, qui est dérivé d'un acide gras. La phase dispersée peut être par exemple, un polymère de vinyle, une polyurée ou un polyuréthane-urée.
