The aim of this article was to determine the effect of the dicumyl peroxide (dicumyl peroxide) content on thermal and mechanical properties of polylactide (PLA). Reactive extrusion of the PLA and dicumyl peroxide blends was performed. The dicumyl peroxide content varied from 0.2 to 1.0 wt.%. The extruded samples were characterized by the Fourier transform infrared spectroscopy (FTIR), analyses of gel content and swelling degree, thermogravimetry (TG), differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), and tensile and impact strength tests. It was found that dicumyl peroxide caused crosslinking of PLA as well as contributed to formation of low-molecular weight products of decomposition and degradation processes. These products caused plasticization of PLA, which led to a decrease in the glass transition temperature. An increase in tensile strength and decrease in impact strength were observed as the dicumyl peroxide content increased.

Dicumyl peroxide Chemical Properties,Uses,Production
Chemical Properties
white powder
Chemical Properties
Dicumyl peroxide is a crystalline solid that melts at 42°C. It is insoluble in water and soluble in vegetable oil and organic solvents . It is used as a high-temperature catalyst in production of polystyrene plastics. The deflagration hazard potential of this peroxide was tested using 5 g of igniter in the revised time–pressure test, but no pressure rise was produced . Noller et al. found it to be an intermediate fire hazard.
General Description
White powder with a characteristic odor.
Reactivity Profile
The explosive instability of the lower dialkyl peroxides (e.g., dimethyl peroxide) and 1,1-bis-peroxides decreases rapidly with increasing chain length and degree of branching, the di-tert-alkyl derivatives being amongst the most stable class of peroxides. Though many 1,1-bis-peroxides have been reported, few have been purified because of the higher explosion hazards compared with the monofunctional peroxides. Dicumyl peroxide is unlikely that this derivative would be particularly unstable compared to other peroxides in it's class, Bretherick 2nd ed., p 44 1979.
Safety Profile
Mildly toxic by ingestion. See also PEROXIDES. When heated to decomposition it emits acrid smoke and irritating fumes.
Purification Methods
Crystallise the peroxide from 95% EtOH (charcoal). Store it at 0o. Potentially EXPLOSIVE. [Beilstein 6 IV 3220.]

Description and features
Iniper DCP (dicumyl peroxide), is a white crystal which has C18H22O2 as chemical formula. This dialkyl peroxide is used for the (co)polymerization of styrene, besides it is used to crosslink polymers and elastomers. Further it finds its application as flame retardant synergist in EPS.
Dicumyl Peroxide is also known as Diisopropylbenzene peroxide, Bis(α,α-dimethylbenzyl) peroxide and Dicumene hydroperoxide.
Storage
Store Dicumyl Peroxide in a cool, dry and well-ventilated area and in line with legal requirements. Keep Iniper DCP away from heat sources, avoid contact with acids, alkalines, heavy metal compounds and reducing agents. The Self Accelerating Decomposition Temperature (SADT) in original packaging is 75ºC.
