Instead of 1,3-butadiene, 1-substituted 1,3-butadienes such as 1,3-pentadiene or 2,4-pentadienoate are also possible to use for the reaction but conjugated trienes are produced in this case.

and 1,3-pentadiene, no low oligomer was isolated and polymers having the above general formula were produced. The chain transfer constant of t-butyl isocyanide in the thermal polymerization of ...
