Crosslinking of polybutadiene rubber without any vulcanization agent.

From: Polymer Engineering and Science | Date: August 1, 1998| Author: Bellander, Martin; Persson, Sture; Stenberg, Bengt | Copyright information

Polybutadiene rubber with 10% vinyl unsaturation has been crosslinked without the addition of any vulcanization chemicals. The crosslinks have been created through treatment at high temperature (240-250 [degrees] C) and elevated pressure ([less than] 293 MPa) in a plunger type mold. The treatment time needed to achieve a crosslinked material is of the order of a few minutes and the reaction rate is shown to be dependent upon the temperature as well as upon the pressure applied. As a result of...
