The present invention relates to preparations having improved efficacy as flame retardants, to the use thereof and to polyurethanes containing the preparations according to the invention.

Preparations having improved efficacy as flame retardants

The present invention relates to phosphoric ester preparations with reduced hygroscopicity, to use of these as flame retardants and hydraulic fluids, and to polyurethanes which comprise the phosphoric ester preparations of the invention.

Phosphoric ester preparations with reduced hygroscopicity

Flame retardant compositions for polyurethanes may include hydroxyl-containing poly(alkylene phosphates) that have 5 mol % or less of phosphorus from phosphorus-containing compounds having aP NMR resonance signal at a chemical shift in the range from 13 ppm to 18 ppm relative to 85 wt % phosphoric acid.

Hydroxyl-containing poly(alkylene phosphates)

The present invention relates to halogen-free oligomer mixtures of poly(alkylene phosphates), production of these and use as flame retardants, and also to flame-retardant polyurethanes comprising halogen-free oligomer mixtures as flame retardants.

Halogen-free poly(alkylene phosphates)

Low-scorch flame-retardant polyurethane foams include phosphorus-containing propionic ester flame retardants. Methods for producing and using the foams are also provided.

Low-scorch flame-retardant polyurethane foams

The present invention relates to timber materials rendered flame-retardant by using halogen-free organophosphorus compounds, to means and processes for producing these materials, and also to their use.

Flame-retardant timber materials

The present invention relates to a composition comprising thermoplastic materials and crosslinked microgels which are not crosslinked by high-energy radiation, processes for its preparation, its use for the production of thermoplastically processable shaped articles and shaped articles produced from the composition.

Microgel-containing thermoplastic elastomer composition

The present invention relates to compatible blends of, per se incompatible, thermoplastic molding compositions, to methods for the production thereof, and to the use of the blends according to the present invention to produce films, fibers and molded articles.

Compatible blends of thermoplastic molding compositions

The invention relates to carbodiimide-based block copolymers, a method of preparing them and also their use as hydrolysis stabilizers in ester-group-containing polymers. The advantages of the block copolymers according to the invention are, in particular, their high efficiency at low dosage as hydrolysis protection in ester-group-containing polymers, and also their nontoxic behavior, their high thermal stability and their good compatibility during incorporation in the polymeric matrix of the polymers to be protected.
