Abstract

The invention relates to a stabilizing composition for halogen-containing polymers containing at least one sodium salt of a dicarboxylic acid from the group of malonic- and/or fumaric acid and/or monoesters thereof.

Description

NaFumarate-NaMalonate

The invention relates to a composition for stabilizing halogen-containing polymers, in particular polyvinyl chloride (PVC) and halogenated resins. in hard-hard and soft applications involving said satellizer composition.

Halogen-containing polymers or plastics or molded articles produced therefrom tend to undergo substantial changes during their production process and due to the effect of environmental influences. For example, these types of plastics may decompose or discolor under the influence of heat and / or light. To stabilize halogen-containing polymers, therefore, a very wide variety of substances or mixtures have already been used.

The basis forms in almost all cases the calcium salt of an organic acid (e.g., technical stearic acid, lauric acid, 2-ethylhexanoic acid, octanoic acid or

Benzoic acid). The calcium salt causes a fundamental stabilization of the halogen-containing polymer by the binding of the liberated hydrochloric acid as calcium chloride. The calcium salt is sometimes also mixed with a magnesium salt on o.g. Base combined or replaced by a magnesium salt.

However, the calcium or magnesium salt may be used in combination with zinc salts based on o.o. organic acids are used. On the one hand, the zinc salts with the formula 1 depicted give the halogen-containing polymer a good color, because they are the labile chlorine atoms on the

CONFIRMATION COPY halogen-containing polymer (PVC) can substitute. Zinc chloride is formed during this reaction. This chloride is known to the chemist as Lewis acids. It is capable of binding more than two chloride ions as shown in Formula 2. As a result, the chloride catalyzes the decomposition of the halogen-containing polymer and reduces the stability.

Formula 1 :

OO PVC-Cl + _{Zn (0} ^ _R ) ₂ ^PVC -O ^ R ⁺ ^ 2

Formula 2:

ZnCl ₂ + 2 HCl - H ₂ [ZnCl ₄ ]

Another reaction of the alkaline earth metal soaps is the displacement of the fatty acid by hydrochloric acid from the salt as shown in Formula 3.

Formula 3:

With different ratios of alkaline earth to zinc salts can be in principle all stabilities and Set initial colors. If the alkaline-earth soap dominates, good stabilities can be achieved with a rather modest initial color. If zinc salts predominate, the color is better, with probably acceptable stability. From the formation of the zinc chloride according to formula 1 or formula 2, which promotes decomposition of the halögerihaltigen ^"polymer, the need for co-stabilizers results in use. This co-stabilizers bind either hydrochloric acid or complexing Lewis acids ie the zinc chloride in this case. Typical co-stabilizers are hydrotalcites , Zeolites, metal (hydr) oxides, polyols, β-diketones, organic phosphites, antioxidants, epoxides, perchlorates etc.

In addition to the above-mentioned metal salts, others have also been used for some time. Thus, EP 0492803 describes the use of disodium adipate (DNA) as a costabilizer for (essentially) tin stabilizers. Thus, it can be seen from Example 1 in this document that the dynamic stability in the measuring mixer (Brabender) increases. The static stability in the oven test can be improved by the addition of DAN; Examples 2-5. However, the initial color (represented by the yellowness index) deteriorates significantly even with small additions. Example 12 shows the color scheme. DNA has a very positive influence on the color retention in comparison to the DNA-free sample. The potassium adipate (Examples 14 and 15) has less stabilizing properties than DNA, which is recognized by the time it takes to blacken. The main disadvantage of THEN is the deterioration of the initial color. EP 2083044 describes the use of DNA in combination with a salt of perchloric acid or of H (CF ₃ S0 ₃ ). Again, the beneficial effect of DNA in combination with sodium perchlorate in terms of color and / or stability. However, zinc stearate and Natriumperchlorate (Example 3) presence, ^"says suffers color stability during prolonged storage in the oven compared to zinc-free example of the second

It has thus been found that in such DNA-stabilized polymers the dynamic and static stability can be improved, but the initial color and the color retention are not always improved and in some cases even worsened. However, in addition to the stability, the initial color and color retention also play an important role for the user and the final product

The present invention is therefore based on the object to provide new stabilizer compositions which are particularly suitable for halogen-containing polymers, without having the above-mentioned disadvantages of the known stabilizers.

This object is achieved according to the invention by the provision of a stabilizer composition based on the sodium salts of fumaric acid and of malonic acid for halogen-containing polymers.

Surprisingly, it has been found that the stabilizer compositions according to the invention halogen-containing polymers and the parts and products made therefrom a very good initial color, a give excellent color retention and increased stability to the effects of sunlight and artificial light.

In particular, the initial color and the color retention of the halogen-containing material can be significantly improved compared to other organic and inorganic costabilizers when used in applications that are used outdoors, for example in window profiles. In addition, it has been found that by using the stabilizer compositions according to the invention moldings of halogen-containing polymers can be prepared without problems which enable optimum performance in use and which with the commodities for PVC stabilization on the basis of heavy metal-containing and -free

Stabilizer compositions are comparable. This stabilizing effect also occurs when the halogen-containing polymer contains further stabilizers, costabilizers or auxiliaries.

In addition, with the stabilizer compositions of the present invention, it is entirely possible

To dispense with heavy metal compounds and still achieve a consistent or even better stability of the halogen-containing polymers. As a result, any pollution to the environment can be reduced and costs for, for example, expensive disposal can be avoided. "Heavy metal-free" in the sense of the present invention means that no compounds with a density of the metal> 4.51 g / mL in the

Stabilizer composition are present, with Zn compounds could be an exception. In particular are Compounds of heavy metals such as tin, lead and / or cadmium are not desirable.

Moreover, the present invention does not contain a compound of the general formula

where X, Y or Z are either hydrogen or optionally substituted with alkyl radicals amino groups. Such compounds are described in WO 2006/110106 Al.

The present invention also relates to the use of the invention

However, it is also possible to add the combination according to the invention together with other (co) stabilizers or the auxiliaries listed below to the polymer or a polymer mixture. For example, metering in the extruder, eg in the vacuum zone, is also encompassed by the present invention.

Examples:

The selection of the examples is based on the examples in EP2083044A1. The selected test substances (both according to the invention and not according to the invention) were prepared in the laboratory and tested in PVC. For this purpose, a dry blend of the following composition was brought to a temperature of 120 ° C. in the course of 5 minutes in a heating refrigerator without additional heating and then cooled to 40 ° C. within a further 5 minutes. Subsequently, the dry blend was stored for 24 h at room temperature.

Homogenized and then on a two-roll mill from the company Collin at a gap width of 0.4 mm, at a rotational speed of both rolls of 10 rpm at 200 ° C within 5 min. plasticized. The color of the rolled skins obtained was (yellowness index in accordance with ASTM D-1925), the stability in the oven (Metrastat at 200 ° C.), the Congo red value (according to DIN VDE 0472D (614) but at 180 ° C.) and DHC value (= dehydrochlorination (according to DIN 53381 at 200 ° C) measured.

In addition, ^" an effectiveness factor was introduced, based on dividing the product of all the properties that are to be as high as possible (DHC, Congo red, oven stability) by the product of all properties that should be as low as possible (YI to 0, 15 and 30) To get a clear, natural number, this quotient was multiplied by 100.
