Tert-Butyl Peroxyneodecanoate

Tert-Butyl Peroxyneodecanoate is a peroxyester organic peroxide used as a free-radical initiator for selected polymerization processes. CAS 26748-41-4 and molecular weight 244.4 g/mol identify the active peroxide. Its decomposition profile is suited to polymerization systems where initiator activity must match reaction temperature and residence time.

Low-Temperature Initiation
The peroxide decomposes within a temperature range suitable for selected low-temperature polymerization processes.

Controlled Decomposition
Half-life data at defined temperatures provide a practical reference for matching initiator activity with polymerization conditions.

Ethylene
Used as a free-radical initiator in selected ethylene polymerization and copolymerization processes.

Vinyl Chloride
Applicable to selected vinyl chloride polymerization systems where the decomposition profile matches the reaction temperature.

Vinylidene Chloride
Used in polymerization systems requiring controlled peroxide initiation at relatively low temperatures.

Acrylates & Methacrylates
Applicable to selected acrylate and methacrylate polymerization processes, subject to formulation and process conditions.

Reaction Temperature
Compare the operating temperature with the 46°C, 64°C and 101°C half-life reference points before establishing the working dosage.

Residence Time
Initiator decomposition should correspond with reactor residence time to achieve the required radical generation during polymerization.

Dosage Level
The working concentration depends on monomer type, polymerization temperature, reactor conditions and target conversion.

Cold Storage
The 95% liquid reference grade has a maximum storage temperature of -10°C. Temperature control should be maintained throughout storage.

Container Control
Keep containers closed and use packaging compatible with the selected peroxide formulation and applicable transport requirements.

Documentation
Storage, handling and transportation conditions should follow the current SDS and technical specification for the supplied grade.

Peroxide Assay
Assay verifies the concentration of active peroxide and provides a primary release parameter for the selected grade.

Active Oxygen
Active oxygen indicates the available peroxide oxygen and supports quantitative batch control.

Appearance & Density
Clear liquid appearance and density at 0°C provide additional physical reference points for incoming and batch quality checks.

Concentration
The peroxide concentration should correspond to the required dosing rate and polymerization process.

Liquid Form
The 95% reference grade is a clear liquid with a density of 0.91 g/cm³ at 0°C.

Technical Documents
Product specification, SDS and applicable quality documentation should correspond to the exact concentration and formulation supplied.

Monomer Compatibility
Confirm the initiator against the monomer, polymerization method and reaction medium before process qualification.

Thermal Profile
The half-life curve provides the basis for assessing decomposition rate at the intended polymerization temperature.

Process Conditions
Temperature, residence time, initiator concentration and target conversion should be evaluated together when establishing the process dosage.

Specification
Provide the required peroxide concentration, polymer system, reaction temperature and expected quantity for technical specification review.

Qualification
Confirm assay, active oxygen, half-life data, storage temperature and documentation before production use.

Delivery
Confirm packaging, temperature-controlled storage and applicable transport conditions according to the selected grade.
