A process for preparing a dispersion of inorganic oxide particles in polyester polyol by mechanically mixing of the inorganic oxide particles at a temperature of more than 160° C. with a polyester polyol having an acid number in the range of from 0.05 to 1.5.

Process for preparing a dispersion of inorganic oxide particles in polyester polyol

A composite material contains a nonwoven layer (i) which contains fibers formed from a first thermoplastic elastomer having meshes with a mesh size in the range from 10 to 100 &#x3bc;m, and a membrane layer (ii) which contains a second thermoplastic elastomer and having a layer thickness of less than 30 &#x3bc;m. The membrane is either pore-free (ii.1) or is porous and has pores with an average pore diameter of less than 2000 nm (ii.2). The membrane (ii) is at least partially in direct contact with the fibers of the nonwoven layer (i) and covers the mesh openings in the nonwoven layer (i) at least partially. The fibers of the first nonwoven layer (i) and the membrane (ii) in the contact area are at least partly joined to one another in an interlocking manner.

A graft macromer, comprising the reaction product of at least one macromer being at least one molecule which comprises in its structure one or more hydroxyl-terminated polyether and/or polyester chains, with at least one grafting compound which comprises in its structure at least one at least monoalkoxylated or at least monohalogenated silyl group and at least one alkyl, cycloalkyl or aryl containing group which is reactive towards the hydroxyl group of the macromer, is used for dispersing e.g. SiOin a polyol.
