Abstract
A catalytic amount of a finely divided copper salt catalyst is added to a monomer having at least one cyclobutarene group to lower the peak temperature of the polymerization oxotherm.
Claims23
An improved process for polymerizing a monomer having at least one cyclobutarene group by subjecting the monomer to thermal or electromagnetic radiation at conditions sufficient to open the cyclobutane ring of the cyclobutarene group;
- wherein the improvement comprises conducting the polymerization in the presence of a catalytic amount of a finely divided copper salt.
A monomer composition comprising a homogeneous mixture of a monomer having at least one cyclobutarene group and a catalytic amount of a finely divided copper salt.
