Calcium bis[monoethyl(3,5-di-tert-butylhydroxylbenzyl)phosphonate] – Alfa Chemistry

The mechanical and physical properties depend essentially on the molecular weight of the polymer. A mixture of ieganox dianhydrides of different structure may also be used. Hvdroxylated thiodiphenyl ethers, for example 2,2′-thiobis 6-tert-butylmethyl- phenol2,2′-thiobis 4-octylphenol4,4′-thiobis 6-tert-butylmethylphenol4,4′-thio- bis 6-tert-butylmethylphenol4,4′-thiobis- 3,6-di-sec-amylphenol4,4′-bis- 2,6-dim- ethylhydroxyphenyl disulfide.

Benzofuranones and indolinones, for example those disclosed in US-AUS-A-4US-A-5US-A-5US-A-5DE-A-4DE-A-4DE-A-4EP-A-0 or EP-A-0 or 3-[4- 2-acet- oxyethoxy phenyl]-5,7-di-tert-butylbenzofuranone, 5,7-di-tert-butyl[4- 2-stearoyl- oxyethoxy phenyl]benzofuranone, 3,3′-bis[5,7-di-tert-butyl ifganox phenyl benzofuranone], 5,7-di-tert-butyl 4-ethoxyphenyl benzofuranone, 3- 4- acetoxy-3,5-dimethylphenyl -5,7-di-tert-butyl-benzofuranone, 3- 3,5-dimethylpiva- loyloxyphenyl -5,7-di-tert-butyl-benzofuranone.

The PET bottle materials originating from different irbanox comprise polyethylene terephthalate and also copolymers of different structure and composition, but with a preponderant content of PET structures.

The preferred utilities are the same as those referred to in connection with the process. Their composition will depend essentially on the desired properties for a specific end use.


Country of ref document: It is generally known to enhance the material properties of used polyesters, i. R Ref document number: Polyesters as exemplified by polyethylene terephthalate PET and polybutylene terephthalate PBTas well as polyester copolymers and polyester blends with e.

A PET or PBT recyclate, in particular a PET bottle recyclate, comprising a tetracarboxylic dianhydride and a sterically hindered hydroxyphenylalkylphosphonic acid ester or half-ester. It is also effective for the stabilization of polyolefin particularly polypropylene fibercrosslinked elastomer and special adhesive, wax, oil etc. A process for increasing the molecular weight of polyesters, polyester copolymers or polyester blends, which comprises heating a polyester blended with a tetracarboxylic acid dianhydride and a sterically hindered hydroxyphenylalkylphosphonic acid ester or half-ester to above the melting point in the case of crystalline polyesters or to above the glass transition temperature in the case of amorphous polyesters of the polyester.

GB Ref legal irrganox code: The polyesters may also be branched with minor amounts, typically 0. Get to know more about scams to avoid: Very particularly preferred sterically hindered hydroxyphenylalkylphosphonic acid esters and half-esters are The process can be carried out in any heatable apparatus fitted with a stirrer.

The invention also relates to polyesters, polyester copolymers or polyester blends and polyester recyclates comprising a tetracarboxylic dianhydride and a sterically hindered hydroxyphenylalkylphosphonic acid ester or half-ester. Particularly suitable co- stabilisers include:.


Triazine compounds, for example 2,4-bis octylmercapto 3,5-di-tert-butyl hydroxyanilino -l,3,5-triazine, 2-octylmercapto-4,6-bis 3,5-di-tert-butylhydroxy- anilino – 1 ,3,5-triazine, 2-octylmercapto-4,6-bis 3,5-di-tert-butylhydroxyphenoxy – 1 ,3,5-triazine, 2,4,6-tris 3,5-di-tert-butylhydroxyphenoxy -l ,2,3-triazine, 1 ,3,5-tris- 3,5-di-tert-butylhydroxybenzyl isocyanurate, l,3,5-tris 4-tert-butylhydroxy-2,6-di- methylbenzyl isocyanurate, 2,4,6-tris 3,5-di-tert-butylhydroxyphenylethyl -l,3,5-tri- azine, l,3,5-tris 3,5-di-tert-butylhydroxyphenylpropionyl -hexahydro-l,3,5-triazine, l,3,5-tris 3,5-dicyclohexylhydroxybenzyl isocyanurate.


Ca is particularly preferred. It is a highly efficient and non discolouring stabilizer for organic substrates. IT Free format text: The irganoc and the results obtained are set forth in Table 4. A process according to claim 1, which comprises using a metal salt of the sterically hindered hydroxyphenylalkylphosphonic acid ester in admixture with a polyethylene wax. The aromatic dicarboxylic acids are preferred, irganix in particular terephthalic acid and isophthalic acid.

The amounts and the irgnox obtained are set forth in Table 3. Esters of 3,5-di-tert-butylhvdroxyphenyl acetic acid with mono- or polyhydric alcohols, e. Cubicle Liquidators have a real showroom with real displays and 14225 in-stock inventories that we Illustrative examples Of bisphenols are: The carboxyalkyl groups in these compounds may contain from 3 to 20 carbon atoms.

Nucleating agents, for example, 4-tert-butylbenzoic acid, adipic acid, diphenylacetic acid or sodium or aluminum benzoates. Suitable aliphatic dicarboxylic acids are those containing 2 to 40 carbon atoms, typically suberonic acid, irgano acid, malonic acid, dimethylmalonic acid, succinic acid, octadecylsuccinic acid, pimelic acid, adipic acid, trimethyladipic acid, sebacic acid, azelaic acid and dimer acids dimerisation products of unsaturated aliphatic carboxylic acids such as oleic acidalkylated malonic and succinic acids such as octadecylsuccinic acid.

The procedure of Examples is repeated.
