摘要:
High density polyethylene is cross-linked with certain cyclic perketals including a group of novel cyclic perketals. Typical of the novel molecules is 3,6,6,9,9-pentamethyl-3-ethylacetate-1,2,4,5-tetraoxy cyclononane.

摘要:
Dialkyl peroxides containing at least one epoxy grouping alpha to the peroxide linkage. Such peroxides have been found to be useful as catalysts in the preparation of heat cured polymer systems such as unsaturated polyester resins.
