Solid Monomers of Polymers

It is recommended that the least amount of solvent required to disperse the solvent be used to avoid formation of cyclic oligomers. Also, if applying vacuum to a solution ADMET polymerization, the vacuum should be applied very carefully to prevent bumping. 

It has recently been demonstrated that ADMET occurs in the solid state. If the ADMET of 1,9-decadiene is carried out at temperatures below 60°C, the polyoctenamer will solidify after an average DP of about 5 is reached. Using the carrier gas method, ADMET continues in this solid for days as proven by GPC analysis. In some cases molecular weights of greater than 70 kDa with complex 10 have been observed by this method. It is not a general method, however, and the scope and limitations are still being explored [106].
