The electric strength of copolymers

  • H. Sabuni
  • J. K. Nelson


Careful measurements of the electric strength of styrene—butadiene copolymers together with their parent homopolymers over a wide range of temperature are presented. The marked reduction of strength characteristic of a non-polar amorphous material occurs at a temperature indistinguishable from the glass transition temperature determined by differential thermal analysis. This temperature may be predicted from the constitution of the copolymer. The underlying mechanism is discussed in terms of molecular structure and movement.
