Process for foaming polymeric compositions with organic azo compounds and compositions associated therewith |
| 摘要 |
Azo compounds such as 2-ethyl-6-methyl-phenylazo-t-butane which contain an aromatic moiety bridged to one or more alkyl moieties by azo groups are useful blowing agents in a novel process for foaming compositions of polymers such as polycarbonates.
