Spray addition during deactivation of polymerization catalysts is particularly advantageous; In this case, the developed steam can be used for catalyst deactivation.

The additives of the invention and other optional additives may also be added to the polymer in the form of a masterbatch containing the components in a concentration, for example from 1 to 40%, preferably from 2 to 20%. by weight incorporated into the polymer. Opolymer does not necessarily have to be identical to the polymer to which additives were finally added. In such operations, the polymer may be used in the form of a powder, granules, solutions, suspensions or as a latex.

Incorporation may occur before or during the shaping operation, or upon application of the dissolved or dispersed polymer compound, with or without subsequent evaporation of the solvent. Another possibility for incorporating the additives of the invention into the polymer substrates is the addition to them before, during or shortly after polymerization of the corresponding monomers or before the crosslinking step. In the present context, the additives of the invention may be added as present or in an encapsulated form (for example, in waxes, oils or polymers).

The polymers containing the additives of the invention described herein may be used for the production of moldings, rotational molded articles, injection molded articles, blow molded articles, similar profiles.

The polymers of the present invention may also optionally contain from 0.01 to 5%, preferably from 0.025 to 2% and especially from 0.1 to 1% by weight of various conventional additives such as , the materials referred to below or mixtures thereof. Antioxidants

Nanoscale or nanocomposite loading agents may also be employed in the present compositions. Thus, "nanoargyls" disclosed, for example, in U.S. Patent Nos. 5,853,886 and 6,020,419 are included.

Nano-scale fillers are, for example, smectite phyllosilicates or clays, for example, organophilic phyllosilicates, naturally occurring phyllosilicates, synthetic phyllosilicates or a mixture of such phyllosilicates. The present nanoscale fillers are, for example, montmorillonites, bentonites, beidelites, hectorites, sa-ponites or stevensites.

For example, nanoscale montmorillonites have a platey or platelet structure. Platelets generally have a thickness below about 2 nm. Platelets or particles generally have an average diameter of from about 20 to about 30,000 nm, and a length to width ratio of from about 30,000: 1 to 20: 1. The commercially available nanoscale montmorillonites in detail are Nanomer® I.42E, available from Nanocor, and Cloisite®30B, available from Southern Clay.

Nanoscale fillers have an extremely large surface with high surface energy. Deactivation of surface energy and compatibilization of the nanoscale polymer filler is therefore even more important than with a common microscale discharge agent in order to avoid coagulation and to obtain excellent dispersion of the polymer. nanoscale filler in the polymer. Nanoscale fillers, such as phyllosilicates, are made organophilic by exchange of ions, for example with alkylammonium salts. These nano-scale organophilic phyllosilicates are more expandable and easier to disperse into a polymer matrix.

Nano-treated filler agents are also referred to as "layered clay treated material" or "organo clay".

The nanoscale filler is present in the compositions of the present invention at a concentration of 0.5 to 10% by weight based on the weight of the polymer or film-forming binder, for example from 1 to 9 wt.%, Preferably from 3 to 7 wt.%, For example 5 wt.%, Based on the weight of the polymer or film-forming binder.

The present polymer compositions exhibit satisfactory wear resistance (heat, oxygen and light stability), scratch resistance, satisfactory processability, satisfactory mechanical strength, satisfactory gloss retention and are non-sticky. Polymer molded parts are suitable, for example, for automotive applications, such as bumper, dashboard and the like.

The present polymer compositions may also be in the form of sheets, as parts of multi-layer structures, as wires or cable insulation, and as films or natural composite products.

The following examples illustrate the invention in greater detail. Unless otherwise indicated, all percentages are expressed in parts by weight.
