Description

Polycarbonate molding materials with good release properties and molded articles and semi-finished products having good sliding properties {Polycarbonate Molding Materials with Good Demoulding Properties and Molded Bodies and Semi-Finished Products with said Materials, with Good Sliding Properties}

Patents and publications describing the release effect of additives on common thermoplastics, in particular polycarbonates, are known. The substances most frequently used as release agents are esters prepared from long chain fatty acids and alcohols. The use of fatty alcohols or polyols, such as pentaerythritol and esters prepared from fatty acids, is described in DE 33 12 158, EP 100 918, EP 103 107, EP 561 629, EP 352 458, EP 436 117, or Guerbet. Alcohols are used in US Pat. No. 5,001,180, DE 33 12 157, US Pat. No. 5,744,626, and in the case where montanic acid is used as acid component, US Pat. No. 4,097,435, respectively.

Fatty acid esters have the disadvantage of exhibiting apparent release effects only in amounts exceeding 0.5% by weight. However, these concentrations are high enough to frequently result in formation of turbid and / or template-like precipitates.

For example, other release agents, such as long chain ketones, tend to form chromophores as a result of internal condensation and are not readily available (EP 100 918).

In addition, the siloxanes used (US 4 536 590, US 4 390 651, US 3 751 519) are sufficiently resistant to high and low temperatures, while having very low compatibility with polycarbonates at effective concentrations, This results in unwanted turbidity that greatly limits the use of common materials such as predominantly tuned polycarbonates.

For example, α-olefin polymers described in EP-A-561 630 and EP-A-230 015 and optionally having residual double bonds (DE-A-32 44 499) are not color stable. In the case of hydrogenated systems such as long chain alkanes (US 4 415 696), compatibility with polycarbonates is a problem, resulting in cloudy and consequently non-transparent shaped articles. Moreover, the waxy or liquid waxy consistency of such products is also inconvenient.

Since warping release of polycarbonate moldings requires shorter cycles and higher processing temperatures, it is often difficult to maintain very high quality surfaces regardless of the wide variety of molding designs. This problem is often overcome only by tailor-made release formulations. Thus, there is a constant need for new and effective release agents.

There are two forces during release work: static and kinetic friction forces. Release agents should be designed to minimize these two forces without forming unwanted deposits on the mold.

The present invention optionally comprises a polycarbonate molding adapted to be easily releaseable, having fatty acid esters based on 1,2-dihydroxypropane and C ₁ -C ₄₀ carboxylic acids as release agents in addition to other additives customary for polycarbonates. To provide a composition.

Accordingly, it is an object of the present invention to find a release agent that can minimize the forces involved in releasing the two releases at the same time, so that the finish of any shape can be released without forming a precipitate on the mold using one molding composition.

It is also an object of the present invention to find release agents which do not tend to transesterify with polycarbonates and which do not lead to turbidity or discoloration at effective concentrations.

It is also an object of the present invention to reduce the problems caused by the attachment of finished polycarbonate molded articles to metal, such as, for example, when removing the beaker after storage.

It is also an object of the present invention to reduce the problems caused by the attachment of finished polycarbonate molded articles to metals, such as, for example, when slipping on inclined metallic surfaces.

It is also an object of the present invention to adjust the adhesion which is important in the case of toys, for example. However, in this case too low adhesion may also be undesirable in some cases, so a precise combination of components must be ensured.

The object of the present invention has been achieved by using 1,2-dihydroxypropane and C ₁ -C ₄₀ carboxylic acid based fatty acid esters having sufficient solubility and stability in polycarbonate as release agents.

The present invention optionally comprises other additives customary for polycarbonates, such as thermal stabilizers, UV stabilizers, other release agents, flame retardants, anti-drip agents, fillers, glass fibers, and ABS, ASA, SAN, EPDM 1, with mixtures of different C ₁ -C ₄₀ carboxylic acids, with the same blend component or with 1,2-dihydroxypropane and C ₁ -C ₄₀ carboxylic acids with polyesters based on terephthalic acid and diol; 0.005 to 5.0% by weight, preferably 0.05 to 3.0% by weight, of esters prepared from 2-dihydroxypropane, in which the alcohol may be partially esterified, as well as a mixture of partially and fully esterified products %, Most particularly preferably from 0.15 to 2.0% by weight, wherein the molding composition is placed on a release force measuring device (friction coefficient measuring device) The coefficient of friction for static and kinetic friction is preferably less than 0.80, particularly preferably less than 0.60, most particularly preferably less than 0.40 (where reference is made to polycarbonates of the same viscosity which do not contain a release agent on the friction coefficient measuring device).

However, it is intended to work with the purest product possible.

When the molding composition contains free OH groups, it is preferred to contain ions of less than 10 ppm, particularly preferably less than 5 ppm. This most particularly applies to ions of elements Na, K, Mg, Ca, Sn, Ti, Fe, Ni and Cr.

If the fatty acids used according to the invention are partially esterified and contain free OH groups, they preferably contain ions below 10 ppm, particularly preferably below 5 ppm. This most particularly applies to ions of elements Na, K, Mg, Ca, Sn, Ti, Fe, Ni and Cr.

The adhesion of the finished polycarbonate molded article is preferably reduced by a release agent content of 1.5% to 2.5% by weight.

Up to 80 mol%, preferably 20 mol% to 50 mol% portions of the carbonate groups in the polycarbonates suitable according to the invention may be substituted by aromatic dicarboxylic acid ester groups.
