    摘要: Disclosed herein is an improved coolant additive having corrosion inhibitive and scale preventative properties. In particular, the inventive additive in its various embodiments is specifically designed to avoid the use of silicates which, as is well known, form deposits which coat the surfaces and passageways of heavy duty diesel and other cooling systems, resulting in shortened life and reduced efficiency thereof. The inventive additive includes sodium hydroxide and/or alkal metal carbonate, ricinoleic acid, Reomet 41, Thiotax, various forms of SMA copolymers, sodium benzoate, sodium nitrate, chelant(s), antifoam agents, dye/pH indicator and soft water (composition solvent), mixed together in predetermined proportions with the various embodiments of the inventive additive including other constituent substances.

    摘要: Water treatment, e.g. antiscaling, polymer compositions are marked or labelled with activated groups which are attached to the polymer chain backbone by carbon-carbon bonds. These activated groups are subjected to color forming reactions, e.g. by reaction with a diazonium aromatic compound, thus enabling the polymers to be detected at very low concentrations in water.

    摘要: A water soluble polymer composition is disclosed. The polymer has repeat units characterized by the structural formulae: ##STR1## wherein R.sub.1 is H or lower alkyl (C.sub.1 -C.sub.3); R.sub.2 is OH, OM, or NH.sub.2 ; M is a water soluble cation; R.sub.3 is a hydroxy substituted alkyl or alkylene radical having from 1 to 6 carbon atoms or a non-substituted alkyl or alkylene radical having from 1 to 6 carbon atoms; X is an anionic radical; Z is H or hydrogens or a water soluble cation or cations which together counterbalance the valence of X, and a is 0 or 1. The copolymer is effective in inhibiting the precipitation of certain scale forming salts, and also acts to inhibit corrosion of metal parts in contact with water systems.
