Peroxides polymeric

Polymeric OC-Oxygen-Substituted Peroxides. Polymeric peroxides (3) are formed from the following reactions ketone and aldehydes with hydrogen peroxide, ozonization of unsaturated compounds, and dehydration of a-hydroxyalkyl hydroperoxides consequendy, a variety of polymeric peroxides of this type exist. Polymeric peroxides are generally viscous Hquids or amorphous soHds, are difficult to characterize, and are prone to explosive decomp o sition. [Pg.116]

The gelling of the vinyl monomers in an aqueous medium in the presence of an organic peroxide polymerization initiator is delayed by using an inhibitor consisting of an alkali metal or ammonium salt of the N-nitroso-phenylhydroxylamine combined with an aminocarboxyUc acid [1179]. [Pg.278]

Using the methods described, the values of Cm and Ci in the benzoyl peroxide polymerization of styrene have been found to be 0.00006 and 0.055 respectively [Mayo et al., 1951]. The amount of chain transfer to monomer that occurs is negligible in this polymerization. The chain-transfer constant for benzoyl peroxide is appreciable, and chain transfer with initiator becomes increasingly important as the initiator concentration increases. These effects are shown in Fig. 3-7, where the contributions of the various sources of chain ends are indicated. The topmost plot shows the total number of polymer molecules per 105 styrene monomer units. The difference between successive plots gives the number of polymer molecules terminated by normal coupling termination, transfer to benzoyl peroxide, and transfer to styrene. [Pg.241]

Acrylonitrile is a colourless liquid with a boiling point of 77-3 C and is sparingly soluble in water. It polymerizes readily in aqueous solution in the presence of a suitable catalyst such as benzoyl peroxide, azo-2-2 -di-iso-butyronitrile, or ferrous sulphate and hydrogen peroxide. Polymerization...
