PROCESS FOR THE MANUFACTURE OF THERMOPLASTIC FOAM CONTAINING HFO-1336MZZ(Z) AND HFO-1336MZZ(E)

Abstract:

This invention relates to processes of preparing thermoplastic foams comprising HFO-1336mzz(E). An exemplary process comprises preparing a thermoplastic foam comprising HFO-1336mzz(E) in the presence of a blowing agent which is HFO-1336mzz(Z) and a co-blowing agent, wherein polymer is heated to a temperature sufficient to isomerize at least a portion of the HFO-1336mzz(Z) to the HFO-1336mzz(E). Thermoplastic foams and foamable compositions comprising HFO-1336mzz(E) are also provided.
