While the ongoing story about new product development has unfolded, the parallel, more technical side of the saga has continued—catalysis, the science that made it all possible. In the early processes through the 1940s, the commercial polymerization processes used free radical, peroxidcr base catalysts to kick off the polymerization reactiom.The popular catalysts included t-butyl peroxypivalate, r-amyl peroxypivalate,. t-butyl hydroperoxide, and t-buryl peroxybenzoate, chemicals you don t run across every day. These catalysts were typically used in high-pressure processes to produce branched LDPE.

An examination of the behavior of peroxides in the course of their rapid thermal decanposition, provides some insight into the nature of the decomposition intermediates and/or products. NMR spectra taken during the thermolysis of various peroxides and per-oxyesters in solution at temperatures where they have short half lives, e.g. benzoyl peroxide and t-butyl peroxypivalate at 110 C, contain emission peaks and/or enhanced absorption peaks. These peaks are presumed to be those of the reaction products resulting from interactions involving the transient decomposition products, e.g. interactions between pairs of caged radicals or from radical pair encounters. The NMR spectra are indicative of the occurrence of chemically induced dynamic nuclear polarization (CIDNP).
