A smoke retarded composition comprising (A) a smoke retardant amount of at least one amine molybdate, the amine used in preparing said amine molybdate containing from 1 to 40 carbon atoms and from 1 to 10 primary, secondary or tertiary amine groups or a mixture thereof, and (B) at least one polymer selected from the group consisting of, polychloroprene, polymonoolefins, halogenated and chlorosulfonated polymonoolefins, poly(vinylacetate), and polymers of acrylonitrile alone or with butadiene and/or styrene.
Claim 2
Dependent Claim
75 words
A smoke retarded composition comprising (A) a smoke retardant amount of at least one amine molybdate, the amine used in preparing said amine molybdate containing from 1 to 40 carbon atoms and from 1 to 10 primary, secondary or tertiary amine groups or a mixture thereof, and (B) at least one polymer selected from the group consisting of, polychloroprene, polymonoolefins, halogenated and chlorosulfonated polymonoolefins, poly(vinylacetate), and polymers of acrylonitrile alone or with butadiene and/or styrene.
