Perodox B

Polymerization of acrylate and methacrylate:

Within the temperature range of 130-175 ℃, it can be used as an initiator forsolution polymerization or copolymerization of acrylate and methacrylate,especially in the production of coatings. It can also be used as an initiatorfor bulk and suspension polymerization or copolymerization of acrylate and methacrylate.

DTBP(Di-tert-butyl peroxide) can be usedfor the market segments: polymer production, polymer crosslinking and acrylics production with their different applications/functions.

The reactivity of an organicperoxide is usually given by its half-life (t½) at various temperatures. For DTBP in chlorobenzene half-life at other temperatures can be calculated by
using the equations and constants mentioned below:

0.1 hr at 164°C (327°F)

1 hr at 141°C (286°F)

10 hr at 121°C (250°F)

Formula 1 kd = A·e-Ea/RT

Formula 2 t½ = (ln2)/kd

Ea 153.46 kJ/mole

A 4.20E+15 s-1

R 8.3142 J/mole·K

T (273.15+°C) K

Organic peroxides are thermallyunstable substances which may undergo self-accelerating decomposition. Thelowest temperature at which self-accelerating decomposition may occur with a substance in the packaging as used for transport is the Self-AcceleratingDecomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test.

SADT 80°C (176°F)

Method The Heat Accumulation Storage Test is a recognized test method for the determination of the SADT of organicperoxides (see Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria - United Nations, New Yorkand Geneva).

Due to the relatively unstablenature of organic peroxides, a loss of quality will occur over a period of time. To minimize the loss of quality, Do Sender Chem recommends a maximum storage temperature (Ts max. ) for each organic peroxide product.

Ts Max. 40°C (104°F) and

Ts Min. -30°C (-22°F) to prevent crystallization

Note When stored according to these recommended storage conditions, Perodox B will remain within the Do Sender Chemspecifications for a period of at least6 months after delivery.
