摘要:
A family of polymeric black colorants is disclosed. The subject colorants are composed of an organic polymer backbone comprised of a plurality of aromatic rings from which depend via azo groups a plurality of chromophore units having the structure ##STR1## wherein M is hydrogen or preferably a cation. These polymeric colorants are water-soluble, and noncrystalline and form dyes and inks that are fast to paper stock.
摘要:
Analogs of the glycoside rebaudioside A are disclosed. These materials have the formula ##STR1## wherein R is a simple physiologically acceptable noncarbohydrate polar organic group. The analogs are sweet and find use as sweeteners.
摘要:
Red colors having the anthraquinone structure ##STR1## are disclosed wherein R.sub.1 and R.sub.2 are independently selected from among hydrogen, halos, lower alkyls, lower alkoxies, nitros, and sulfonates, and R.sub.3 and R.sub.4 are independently selected from hydrogens, alkyls and alkylsulfonates. Precursors are disclosed as well. In a preferred embodiment R.sub.4 is an alkyl-containing polymer linking a plurality of anthraquinones into a polymeric colorant especially useful as a nonabsorbable colorant for edibles.
摘要:
Dihydrochalcones of the formula ##STR1## are disclosed wherein X is H or OH and R is lower alkyl. These materials are useful as sweeteners for edibles. A process for preparing these compounds using a novel intermediate is disclosed as are acid and base neutralization products of the subject dihydrochalcones.
摘要:
Poly(vinylamine salts of mineral acids are produced by reacting acetaldehyde and acetamide at a mole ratio of 1:2-4 with acid catalyst, cracking the ethylidene-bisacetamide which results into vinylacetamide, polymerizing the vinylacetamide with a free radical polymerization catalyst, and hydrolyzing the poly(vinylacetamide) to the desired amine salts by contacting the polyvinylacetamide with an aqueous solution of the corresponding mineral acid. This product may be converted to the free amine, which in turn may function as a precursor in the manufacture of certain polymeric dyes and colorants.
摘要:
Viscoelastic materials are differently colored in zones with polymric dyes. When a polymeric dye is added to a zone of a viscoelastic material it does not migrate from the zone; thus permitting an essentially permanently multizoned colored product.
摘要:
N-substituted maleimide polymers comprising the recurring structural units: ##STR1## wherein R and R' independently are lower alkyl groups of from 1 to 5 carbon atoms and n is an integer of from about 2 to about 2,000, are disclosed. Their preparation as well as the preparation of their monomer precursors and the preferred use of the polymers as antioxidants, particularly nonabsorbable food antioxidants, are also disclosed.
摘要:
Polymeric hydroquinones of the structure ##STR1## , wherein n is from 3 to 10,000 inclusive and R and R' independently are hydrogen or a lower alkyl, are disclosed, as is the preparation and the use of such materials, especially as nonabsorbable polymeric antioxidants for edible materials.
