Usage

Performance

2,2′-methylenebis(6-tert-butyl-4-methylphenol) monoacrylate, (also known under the trade names Sumilizer GM, BNX 3052, and Irganox 3052), is a heat and light stabilizer and an antioxidant used in a wide range of adhesive, plastic, and elastomer materials. Unlike traditional phenolic stabilizers/antioxidants, this substance is an effective alkyl radical scavenger. This property is especially useful in processes at high temperatures and in low oxygen environments, such as during the initial mixing of adhesives.The stabilizing mechanism involves trapping of polymer alkyl radicals at the double bond of the acrylate group, and subsequent hydrogen transfer from the intramolecular hydrogen-bonded phenolic hydroxyl group, which results in a stable phenoxyl radical. 2,2′-methylenebis(6-tert-butyl-4-methylphenol) monoacrylate may also be grafted using the acrylate moeity.

Description

Irganox 3052 is an antioxidant. It contains 2-(1,1-dimethylethyl)-6-[[3-(1,1-dimethylethyl)-2-hydroxy-5-methylphenylymethyl-4-methylphenyl acrylate. It is non-staining, non-discoloring, has a low volatility and is resistant to extraction. It protects organic substrates against both, thermo-oxidative and purely thermal degradation. It is particularly active under high processing temperature and anaerobic polymerization and processing conditions. It is compatible with HIPS, ABS, BR, IIR, SBR, SBS, SEBS, EPDM, EPM, MBS, MABS, SMA, modified acrylate, hydrocarbon resins, terpene, terpene phenolic resins, rosin, polycarbonates, polyester-carbonates, polymethacrylates, polyolefins, polyamides or polyphenyleneoxides. Irganox 3052 is suitable for food contact applications. It is listed in AICS, EINECS, PICCS, DSL, MITI, TSCA, CHINA and ECL.

Uses

Irganox 3052 has been used in to study the mechanical properties and performance of stretch films of plasticized PVC and non-PVC alternatives used for retail fresh meat packaging; heat stabilizers for butadiene-styrene copolymers;

Phenol composition and thermoplastic polymer composition comprising the composition

Recently, further improved process stability for thermoplastic polymer compositions has been demanded. Phenol compositions are provided comprising a compound represented by the formula (1): in the formula (1), R1 and R2 are each ind

Production of bisphenol monoester

A bisphenol monoester represented by the formula (I): STR1 wherein R1 is hydrogen or alkyl, R2 and R3 are each alkyl, and R4 is alkyl, alkenyl or phenyl, is produced by continuous two step reactions in which an aldehyde R1 -CHO and 2,4-dialkylphenol are subjected to a condensation reaction in a C6 -C10 aliphatic or C6 -C12 aromatic hydrocarbon solvent, and then a resulting bisphenol compound dissolved in the solvent is subjected to an esterification with a carboxylic acid R4 --COOH or its derivative. Prior to the esterification, the organic layer containing the bisphenol compound is subjected to a dehydration treatment, thereby enabling the two steps to proceed continuously without isolating the intermediate bisphenol compound. A purification process for the bisphenol monoester of the formula (I) is also disclosed in which the monoester is purified from a mixed solvent comprising a C6 -C12 aromatic hydrocarbon solvent and a C1 -C8 alcohol or C2 -C3 aliphatic nitrile solvent.
