SynopsisThe influence of high temperature (160-250OC) on diallyl phthalate polymerization has been investigated. Polymerization was carried out in a nitrogen atmosphere both with and without benzoyl peroxide as initiator, and also in a air atmosphere. A considerable increase in the conversion degree to the gelation point with a parallel increase in temperature has been established. Unsaturation degree of prepolymers remains unchanged independently of temperature and the way of polymerization initiation.
