ACD 1961 R This disclosure relates to a process for cross-linking polymers, e.g. polyethylene, or degrading polymers, e.g. polypropylene, using peroxides having at least one carbon-carbon double bond in the molecule, e.g. 1-(t-butyl peroxy isopropyl)-3-isopropenylbenzene. Incorporation of the peroxides into the polymer may be carried out at relatively high temperatures without the risk of premature decomposition of the peroxide, thus allowing easy processability of the polymer mass prior to cross-linking or degradation. The polymeric endproducts obtained are odourless and do not display blooming. |
