Abstract

1403455 Stabilizing norbornene compounds SUMITOMO CHEMICAL CO Ltd 25 Jan 1973 [27 Jan 1972] 3910/73 Heading C5E Alkenyl- and alkylidene norbornenes are stabilized by adding a 1-naphthol of the general Formula (I) wherein R 9 to R 15 are each H, C 1 -C 9 alkyl or phenyl. The stabilizer may be used in amount 20-3000 p.p.m. Stabilizers used in the examples to stabilize 5-ethylidene-, 5-vinyl-, 5- isopropenyl- and 5-isopropyl-2-norbornenes are 1-naphthol; 2-methyl-1-naphthol; 4- ethyl-1-naphthol; 6-ethyl-2,4-dimethyl-l-naphthol; 4-t-butyl-1 -naphthol; and 4-phenyl-1- naphthol.
