Title Temperature Increase with Neck Propagation in Polymers
Author(s) S.L. Bazhenov (Institute of Chemical Physics, Kosygin 4, Moscow, Russia, bazhenov_sl@rambler.ru)
Abstract The heating arising in the neck propagation in polymers is investigated. The heat equation describing the neck temperature is modified. An analytic solution describing the maximum temperature of the neck is obtained. A method for determining the heat transfer coefficient is developed. The neck heating temperature in polyethylene terephthalate can attain 155°C which is much greater than it is usually thought. The corresponding value for polycarbonate is only 31°C.
