Polymer-modified polyols, a method of forming them, their use in the manufacture of polyurethane products and the products so obtained. |
摘要 |
<p>A polymer-modified polyol comprises a dispersion in a first polyol which has a molecular weight of at least 1000, an average functionality of more than 2, and a Hydroxyl Number of less than 150. of the reaction product of a polyisocyanate and a second polyol which is either (a) a polyethylene glycol having a molecular weight of up to 600 or (b) a polyol, which is not a polyethylene glycol, and which has a molecular weight of less than 250 and is free from nitrogen atoms.</p><p>A method of forming the polymer-modified polyol, its use in the manufacture of polyurethane products and the polyurethane products so obtained, are included.</p><p>The dispersions are particularly useful for preparing highly resilient flexible foams.</p> |
