    Abstract: Macromolecular organic compounds (defined as having a molecular weight corresponding to a K-value of 20 or more) are optically brightened by the homogeneous distribution therein of a 1,4-bis-styryl-benzene which contains on at least one benzene nucleus at least one of the substituents, alkyl, aryl, aralkyl, halogen, hydroxyl, esterified hydroxyl and etherified hydroxyl but no nitrile group or carboxylic acid ester or amide group in which the carbonyl carbon atom is attached to the 1,4-bis-styryl-benzene. The bis-styryl-benzenes may be prepared as described in Specification 813,539. An extensive list of macromolecular substances contain various examples of substances within the general categories:-polyamides; polyaldehydes; polyesters; polycarbonates; amino-formaldehyde polycondensates; unsaturated polyester resins; polymers of dienes, vinyl and allyl esters, vinyl ketones, vinyl ethers, olefinic hydrocarbons and their aryl- and halo-substitution derivatives, olefincally unsaturated mono- and di-carboxylic acids and their esters, amides and nitriles, and vinyl pyridine, carbazole and lactams; regenerated cellulose; cellulose esters; rubber; and chlorinated rubber. In specific examples the optical bleaches are incorporated in the following compositions:-(Examples 1 to 4) polyvinyl chloride, ethoxylated maitonic acid and diphenylthiourea; (Examples 5 and 6) polypropylene and titanium dioxide; (Example 7) polypropylene; (Example 8) a polyamide from caprylic lactam; (Example 9) a lacquer of a styrene-butyl acrylate copolymer in toluene; (Example 10) polyvinyl chloride, ethoxylated montanic acid, diphenylthiourea and titanium dioxide; (Example 11) polyvinyl chloride, dioctylphthalate, titanium dioxide and phenylurea; and (Example 12) a styrene-acrylo-nitrile copolymer, titanium dioxide and barium stearate.

    Abstract: A mixture stabilized against heat and light comprises 99.99 to 95% by weight of a linear polyamide, polyurethane or polyurea and 0.01 to 5% by weight of a bis-styryl benzene or a stilbene, each of which bears 1 to 5-OR radicals attached directly to the benzene nuclei, R being hydrogen, an alkyl group with 1 to 4 carbon atoms, a cycloalkyl group with 4 to 7 carbon atoms, an aralkyl group with 7 to 10 carbon atoms or -(CH2)n-owhere n is an integer from 1 to 4 and the oxygen atoms are attached in the o-position. Many polymers and stabilizers are specified. In the examples: (1), (2), (3), (7), (9) and (13) hexamethylene diammonium adipate and e -caprolactam are co-polymerized in the presence of:-(1) and (3) 3:4-methylene-dioxy-41-carbomethoxystilbene; (3) 3-methoxy-4-hydroxy-41-carbomethoxystilbene; (7) (a) 1:4-bis-(31:41-methylene dioxystyryl) benzene; (b) 1:3-bis(31:41-methylene dioxystyryl) benzene; (c) 1:4-bis(4-a -tetrahydrofuranyloxystyryl) benzene; (d) 1:4-bis(4-hydroxystyryl) benzene; (9) 1:4-bis(31:41\h -methylene dioxystyryl) benzene and (13) 1:2-bis-(3:41-methylene-dioxystyryl) benzene. In the remaining examples: (4)3:4-methylene dioxy-31-carbomethoxystilbene is mixed with polycaprylic lactam; (5) 3:4-methylene dioxy-31-carbomethoxystilbene is mixed with polyhexamethylene adipamide; (6) 3:4-methylene dioxy-31-carbomethoxystilbene is mixed with polyo -aminoundecanoic acid; (8) 1:4-bis(31:41-methylene dioxy-b -cyano-styryl) benzene is mixed with poly-e -caprolactam; (10) 1:4-bis-(31:41 -methylene-dioxystyryl) benzene is mixed with polycapryllic lactam; (11) 1:4-bis-(31:41-methylene dioxystyryl) benzene is mixed with polyhexamethylene adipamide and (12) 1:4-bis-(31:41-methylene dioxystyryl) benzene is mixed with polyo -aminoundecanoic acid.
