    摘要: The use of a small amount of a salicylate dissolved in cellulose ester dopes has been found to result in the stabilization of such dopes to a significant extent against the undesired formation of amber or brownish-red insoluble globules in the dope.

    摘要: STABILIZATION OF ORGANIC PLASTIC SUBSTRATES VERSUS THE DEGRADING EFFECTS OF ULTRAVIOLET LIGHT IS EFFECTED BY INCORPORATING THEREIN STABILIZING AMOUNTS OF A P-METHOXYBENZYLIDENEMALONIC ACID DIESTER REPRESENTED BY FORMULA:

    1-(CH3-O-),4-(R-OOC-C(-COO-R)=CH-)BENZENE

    WHERE R IS A METHYL OR ETHYL RADICAL.
