- the invention relates to the use of the molding compositions according to the invention for the production of fibers, films and moldings of any kind, as well as the moldings obtainable in this case.
- Polycarbonates are usually obtained from the reaction of alcohols with phosgene or from the transesterification of alcohols or phenols with dialkyl or diaryl carbonates.
- aromatic polycarbonates which are produced for example from bisphenols, aliphatic Poiycarbonate play from the market volume heretofore a minor role. See also Becker / Braun, Kunststoff-Handbuch Bd. 3/1, polycarbonates, polyacetals, polyesters, cellulose esters, Carl Hanser Verlag, Kunststoff 1992, pages 118-119.
- the aliphatic polycarbonates described are generally linear or else built up with a low degree of branching.

- Hyperbranched polycarbonates can also be prepared according to WO 98/50453. According to the process described therein, triols are in turn reacted with carbonyl bisimine dazole. Initially, imidazolides are formed, which then react further intermolecularly with the polycarbonates. According to the mentioned method, the polycarbonates are obtained as colorless or pale yellow rubbery products.
- the hyperbranched products are either high-melting or gum-miartig, thereby a later processability is significantly limited.

- graft-crosslinking monomers examples include allyl-containing monomers, in particular allyl esters of ethylenically unsaturated carboxylic acids, such as allyl acrylate, allyl methacrylate, diallyl maleate, diallyl fumarate, diallyl itaconate or the corresponding monoallyl compounds of these dicarboxylic acids.
- allyl-containing monomers such as allyl acrylate, allyl methacrylate, diallyl maleate, diallyl fumarate, diallyl itaconate or the corresponding monoallyl compounds of these dicarboxylic acids.
- allyl-containing monomers in particular allyl esters of ethylenically unsaturated carboxylic acids, such as allyl acrylate, allyl methacrylate, diallyl maleate, diallyl fumarate, diallyl itaconate or the corresponding monoallyl compounds of these dicarboxylic acids.
- the proportion of these crosslinking monomers in the component C) is up to 5% by weight, preferably not more than 3% by weight, based on C).
- graft polymers having a core and at least one outer shell are listed.
- graft polymers having a core and at least one outer shell are to be mentioned here, which have the following structure:
- graft polymers having a multi-shell structure instead of graft polymers having a multi-shell structure, homogeneous, i. single-shell elastomers of buta-1, 3-diene, isoprene and n-butyl acrylate or copolymers thereof are used. These products can also be prepared by Mit ⁇ use of crosslinking monomers or monomers having reactive groups.
- the described elastomers C) can also be prepared by other conventional methods, e.g. by suspension polymerization.
- thermoplastic polyurethanes for example wel ⁇ che.
- EP-A 115 846, EP-A 115 847 and EP-A 117 664 are described.
- the molding compositions of the invention may contain other conventional additives and processing aids.
- additives for trapping formaldehyde formaldehyde (formaldehyde scavengers), plasticizers, adhesion promoters and pigments may be mentioned here by way of example only.
- the proportion of such additives is generally in the range of 0.001 to 5 wt .-%.
- thermoplastic molding compositions according to the invention is carried out by mixing the components in a conventional manner, which is why detailed information is unnecessary here.
- the mixture of the components takes place on an extruder.
- Component B) and, if appropriate, component (s) C) can, in a preferred preparation form, preferably be applied to the granules of A) at room temperatures and then extruded.
- moldings including semi-finished products, films, films and foams
- the molding compounds are characterized by a very low residual formaldehyde content combined with good mechanical properties and thermal stability.
- the processing of the individual components without clumping or caking) is possible without problems and in short cycle times, so that in particular thin-walled components come into consideration as an application.
- the reduction of injection pressures reduces the displacement of the insert in the case of encapsulation of (for example, metallic) inserts, thus improving the dimensional accuracy and service properties and reducing the production scrap.
- Valve body and valve housing for toilet flushing Outlet fittings and functional parts of fittings e.g. hand mixers
- Liquid containers, lids and closures for liquids i.a. in motor vehicle construction
- Transmission electron microscopy was used to study the morphology of selected compounds. It showed a good dispersion of the particles in the blend. Particle sizes of 20 to 500 nm were observed.
- Irganox® 245 from Ciba Geigy:
- Synthetic Mg silicate (Ambosol® company Societe Nobel, Puteaux) having the following properties:
- reaction products were then analyzed by gel permeation chromatography, eluent was dimethylacetamide, polymethylmethacrylate (PMMA) was used as standard.
- PMMA polymethylmethacrylate
- TMP trismethylolpropane
- DEC diethyl carbonate
- PO propylene oxide
- EO ethylene oxide
- Comp. A (Ultraform® N 2320 003, registered trademark of BASF Aktiengesellschaft) contained in each case: 0.35 C1 0.04 C2 0.05 C3 0.14 C4 0.2 C5
- H-PSA cyclohexane-i ⁇ -dicarboxylic anhydride
- TMP tris-hydroxymethylpropane
- CHDM cyclohexanedimethylol
- Component A see Table 1
- Component B 2/1 see Table 1
- HPSA hydrogenated phthalic anhydride
- TMP trimethylolpropane
- CHDM cyclohexanedimethanol
- polyesters were analyzed by gel permeation chromatography with a refractometer as detector. Tetrahydrofuran was used as the mobile phase; polymethyl methacrylate (PMMA) was used as the standard for determining the molecular weight. The determination of the acid number and the OH number was carried out according to DIN 53240, part 2.
