The first thermoplastic mouldable material contains a catalyst for catalysing the formation of covalent liaisons between a thermoplastic polymer and the multifilament surface and, if necessary another additive which has no a detrimental influence on the catalyst activity, the second thermoplastic mouldable material containing additives.

[PAPKE NICOLAI] DE Catalysts which contain no boron and are not Bronsted acids are used in polyacetal molding materials (I) containing (a) 20-99 wt% polyacetal homo- or co-polymer, (b) 0.1-80 wt% additive and (c) up to 1.0 wt% catalyst for reaction between the matrix polymer (I) and the surface of the additive. An Independent claim is also included for molded products obtained from (I).

[PAPKE, Nicolai] Am Unisys-Park 165843 Sulzbach, Taunus Polymer particles containing a polyoxymethylene polymer for coating metallic substrates are described. The polymeric particles contain a polyoxymethylene polymer in combination with a thermoplastic elastomer. The thermoplastic elastomer can include hard segments and soft segernets. The soft segments may contain carbonate groups, ether groups, or caprolactone groups. Also disclosed is a process where the polymeric particles are used to form a fluidized bed for coating metallic substrates. In one embodiment, after being coated with the polymer particles, the coated metal substrate is gas cooled followed by cooling the coated substrate in a bath containing an aqueous medium.

The polymeric particles contain a polyoxymethylene polymer in combination with an adhesion promoter which may comprise an acid modified polyolefin and performance enhancing additives. The polyoxymethylene polymer and the adhesion promoter may also be combined with a thermoplastic elastomer and optionally a coupling agent.
