Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to stabilized compositions of polyolefins, particularly polyolefin compositions that are resistant to degradation due to contact with heavy metals.

Conventionally, polyolefins such as polyethylene, polypropylene, and polybutene have been used in many fields because they have excellent physical and chemical properties.

At this time, as is well known, when polyolefin is used alone, it deteriorates due to heat, light, or oxygen during processing or use, so various antioxidants have been developed and used to prevent this. . However, in cases where contact between polyolefin and heavy metals such as copper, iron, and nickel cannot be avoided, such as when coating copper wire with polyolefin, plating polyolefin with heavy metals, or coloring polyolefin with pigments containing heavy metals, However, the mere use of the above-mentioned conventional antioxidants shows little resistance to deterioration due to contact between polyolefins and heavy metals.

Furthermore, in cases where there is a risk of liquid amorphous polyolefin coming into contact with copper, such as when liquid amorphous polyolefin is used as an insulating oil for cables, resistance to deterioration due to contact with copper is required. However, this requirement cannot be met simply by using the conventional antioxidants.

Therefore, in order to give polyolefins resistance to deterioration caused by heavy metals, N.N'-dibenzoylhydrazine, N-penzoyl-N'-salicyloylhydrazine, N.N'-dibutyrylhydrazine, N.N'-dibenzoylhydrazine, N.N'-dibutyrylhydrazine, N.N'-dibutyrylhydrazine, and ′−
Distearoylhydrazine, N・N'-bis[8-(3
・5-di-tert-butyl-4-hydroxyphenyl)propionyl]hydrazine, N.N'-bissalycyloylhydrazine, oxalobis(benzylidenehydrazide),
Although deterioration inhibitors such as N-salicylidene and N'-salicyloylhydrazine have been developed, the deterioration prevention effects of these agents are still not satisfactory.

The inventors used 100 parts by weight of polyolefin and the general formula [where RI is an alkyl group having 1 to 4 carbon atoms,
R2 is an alkyl group having 1 to 18 carbon atoms, a pyridyl group, or a general formula (m is 0, 1 or 2, R3, R4 and R5
are each a hydrogen atom, a hydroxyl group, or an alkyl group having 1 to 4 carbon atoms).

It was discovered that a composition consisting of 0.001 to 5 parts by weight of the compound (deterioration inhibitor) represented by Completed the invention of a lever. The polyolefins used in this invention include amorphous or crystalline homopolymers or copolymers of olefins such as ethylene, propylene, butene-1, isobutene, pentene-1, and 4-methylbentene-1, and combinations of these olefins and unsaturated carboxylic acids. Alkyl esters such as methyl acrylate, methyl acrylate, methyl methacrylate, ethyl methacrylate or vinyl esters of saturated carboxylic acids such as copolymers with vinyl acetate, mixtures of these various polymers, and also propylene, butene, etc. Examples include liquid amorphous polymers such as.

The deterioration inhibitor in this invention can be easily obtained, for example, by the following reaction.

The reaction represented by formula m and the reaction represented by formula '2} both involve N-dimethylacetamide, dimethylformamide, benzene, toluene, chloroform, ethyl acetate, dichlorobenzene, methylene chloride, carbon tetrachloride,
It proceeds at a temperature of 0 to 100°C, preferably 20 to 60°C, in the presence or absence of a solvent such as tetrahydrofuran.

In order to isolate the deterioration inhibitor of the present invention from the reactive component mixture after the reaction, for example, the reaction product mixture is poured into a large excess of water, the precipitated solid is collected in a furnace, and this furnace collection is washed with water. The solid obtained is dissolved in a suitable solvent such as benzene,
Hydrocarbons such as toluene and n-hexanone, lower alcohols such as methanol and ethanol or their aqueous solutions, lower fatty acids such as acetic acid and propionic acid or their aqueous solutions, N-dialkyl acid amides such as N-dimethylacetamide and dimethylformamide. Alternatively, it may be recrystallized using a recrystallization solvent such as an aqueous solution thereof. Specific examples of suitable anti-deterioration agents in this invention include N-(

In this invention, the amount of the anti-deterioration agent added to the polyolefin is 0.00 parts by weight based on 10 parts by weight of the polyolefin.
The amount ranges from 0.01 to 5 parts by weight, preferably from 0.01 to 3 parts by weight.

If the amount is less than 0.001 parts by weight, the deterioration prevention effect is insufficient, and if the amount is more than 5 parts by weight, no improvement in the deterioration prevention effect is observed. The deterioration inhibitor may be blended into the polyolefin by any method suitable for making a uniform composition, such as dissolving or dispersing the deterioration inhibitor in a low boiling point solvent, mixing it with the polyolefin, and then removing the solvent by volatilization. Alternatively, the polyolefin may be heated to a temperature higher than its melting point on a hot roll and then mixed with the deterioration inhibitor, or the polyolefin and the deterioration inhibitor may be mixed using various types of mixers.

Moreover, the anti-deterioration agent in this invention can also be used in combination with conventionally known stabilizers, dispersants, plasticizers, antistatic agents, fillers, pigments, and the like.
