Usage

Description

ANTIOXIDANT 1035 is a sulfur containing primary antioxidant and heat stabilizer which is widely used for the process stabilization of polyethylene wire and cable resin applications. It eliminates the concern over micro-contaminants that can affect the insulation properties of the wire, and it also prevents premature gel formation of chemically cross-linked polyethylene during extrusion compounding. It also provides efficient processing stabilization and long-term thermal stability with excellent system compatibility and low color in styrenic polymers, polypropylene, polyurethanes, polyesters, segmented block copolymers, other rubber modified polymers, and elastomers (including EPDM, SBR, carboxylated SBR latex, and polybutadiene and polyisopropene rubber). It also provides excellent stabilization in petroleum-based products, including lubricants (such as turbine oils) petrolatum and higher poly alpha-olefins.

Chemical Properties

Antioxidant 1035 is a sulfur containing primary (phenolic) antioxidant and heat stabilizer, provides efficient processing stabilization and long-term thermal stability with excellent system compatibility, low color and low volatile.

Synthesis method of thiodiethylene bis [3-(3, 5-di-tert-butyl-4-hydroxyphenyl) propionate]

The invention relates to a synthesis method of thiodiethylene bis [3-(3, 5-di-tert-butyl-4-hydroxyphenyl) propionate]. The method comprises the following steps: enabling 2, 6-di-tert-butylphenol to react with acrylate, and continuing to react with 2-chloroethanol, so as to obtain an intermediate 3-(3, 5-di-tert-butyl-4-tetrahydroxyphenyl) propionic acid 2-chloroethyl ester; and reacting with sodium sulfide in the presence of quaternary ammonium salt to obtain a target product. The synthesis method disclosed by the invention has the advantages of simple process, high product yield and high purity, and is particularly suitable for being applied to industrial production.

Organothioethyl alcohol segmers as antidegradant synergists

This invention is concerned with the stabilization of organic materials subject to oxidative degradation. The synergists of this invention possess organothioethyl alcohol segmers or moieties which enhance the antioxidative activity of phenolic and amine stabilizers. The invention is also concerned with compounds that contain an organothioethyl alcohol moiety and their use in oxidizable materials in combination with polymerizable and/or conventional antidegradants.

Compositions containing antimicorbial agents in combination with stabilizers

Composition of an antimicrobial agent and an antioxidant having improved antimicrobial activity compared to the antimicrobial agent alone. The preferred environment of the invention is a composition of a thermoplastic resin, an antioxidant, and an antimicrobial agent, the latter two being compatible with the resin. The resin composition can contain other usual additives, and can be melt processed at an elevated temperature to form articles such as films or fibers having improved antimicrobial activity. A method for improving the efficacy of an antimicrobial agent by combining it with an antioxidant is disclosed. A method for melt-processing a resin composition containing an antimicrobial material is also disclosed, wherein the resin composition includes an antioxidant. The inventors have thus discovered and solved the problem of oxidation of an antimicrobial composition, particularly a resin composition containing an antimicrobial agent, which arises when the composition is processed at elevated temperatures, as are typically encountered when forming a fiber or film of the composition.
