Abstract: The moulding compsns. based on linear thermoplastic polyester (I) contg. flame retardant (II) and fibrous reinforcing filler (III) contains K titanate fibres as (III). The K titanate fibres pref. are 0.1-0.15 mu m. in dia., have a length/thickness ratio of ca. 40:1 and are used in an amt. of 5-20wt.% w.r.t. the total wt. of the moulding compsn. Polyester esp. polybutylene terephthalate compsns. can be prevented from dripping on burning without the addn. of asbestos. The compsns. can be processed on all the usual machines, e.g., extruders, rollers or kneaders.

Abstract: A process for making a polyurethane which comprises reacting an organic polyisocyanate with a higher molecular weight organic polyhydroxyl compound in the presence of a catalyst having the following formula: wherein X is sulfur or NH and n is a whole number from 2 to 6. Also used is a catalyst which is a combination of the above-mentioned catalyst and an organic tin compound.

Abstract: A process for separating hydrophobic organic liquids from water comprising passing a mixture of water and hydrophobic organic liquids through a column-like vessel which is filled with a hydrophobic, preferably open-celled, polyurethane foam, said foam having a high absorption capacity, permits high flow-through velocities even as the foam becomes covered and saturated with the hydrophobic organic liquids, is reversibly deformable, and can be reused.

Abstract: Storage-stable, liquid carbodiimide-modified polyisocyanates are prepared by condensation of polyisocyanates in the presence of catalytic amounts of phospholine, phospholidine, phospholine oxides and/or phospholidine oxides, said condensation terminated and the products stabilized by means of perchloric acid or trifluoromethanesulfonic acid.

Abstract: Hydrophobic polyurethane foams which have densities of from 4 to 15 g/liter and in which the number of closed cells is from 2 to 30%, and the number of open cells from 98 to 70%, based on the total number of cells, are obtained from polyisocyanates, polyhydroxy compounds, catalysts and water, with or without lipophilic compounds, the components being reacted in such amounts that the ratio of hydrogen atoms capable of undergoing a Zerewitinoff reaction to NCO groups is from 1.3 to 10:1. The foams are suitable for the absorption of oil and/or by hydrophobic solvents, which may or may not contain halogen, from water.
