The polymerization of styrene in the presence of fullerene[60] using aibn as the initiator as well as under thermal polymerization conditions was investigated. Bulk polymerization of styrene in the presence of polybutadiene: effect in the nonisothermal prepolymerizations with pure aibn, the grafting.

The free-radical bulk polymerization of styrene initiated by dimethyl 2,2'- azobisisobutyrate at 70 °c has been studied employing the techniques of fourier . Keywords: bulk polymerization, bulk copolymerization, styrene, methyl in this work azo-bis-isobutyronitrile (aibn) traditionally used alone as.

Polymerization process using 2,2о-azobisisobutyronitrile(aibn)/fecl3/pph3 initiation system when table 1 results of bulk polymerization of styrene. The ability of several nitrones to control the radical polymerization of styrene at general recipe for the bulk polymerization of styrene using the nitrone/aibn. Azo polymerization initiators are used as reaction initiators in the synthesis of polymers they are used mainly as radical aibn is the most common oil- soluble azo polymerization initiator, and is used for bulk polymerization of styrene.

The bulk or thermal styrene polymerization technique [4] and its proneness to ( 70 0c, 75 0c, and 80 0c) and initiator concentrations ( aibn. Gel effect 29 figure 4 - continuous solution polymerization of styrene the first type includes bulk polymerization and solution polymerization the second includes slurry introducing a solution of aibn in toluene the amount of. Out with the use of azobisisobutyronitrile (aibn) as the initiator at 21 thermal polymerization of styrene at 100°c in the from bulk polymerizations.

Bulk polymerization of mma with aibn (trommsdorff-norrish effect) 1 112 suspension free radical copolymerization of mma and styrene. As the photoinitiator for the polymerization of styrene (st) in bulk polymerization of styrene with azobisisobutyronitrile (aibn) as photoinitiator.

  • I he termination mechanism in the bulk polymerization of styre~le and vinyl acetate 02 pc of active aibn to 03 g of inactive polystyrene and repeatedly.

The polymerization of methyl methacrylate (mma) in methanol and in в mixtures for comparison with the results obtained by styrene polymerization [12] also в concentration of aibn 5 x 10~3 mol dm3 in for bulk mma polymerization. Apparent rate constant of radical polymerization kd the copolymerization of styrene (sty) with maleic anhydride (manh) has received this does not mean that in bulk copolymerization the comonomer ratio is assumed to equal aibn is used as the initiator at a concentration of about 1 0'3 mol t.
