Abstract: The invention relates to a process for improving the pyrolytic conversion of waste selected from rubber and plastic to low molecular weight olefinic materials by employing basis salt catalysts in the waste mixture. The salts comprise alkali or alkaline earth compounds, particularly sodium carbonate, in an amount of greater than about 1 weight percent based on the waste feed.

Abstract: An improvement in a process for the pyrolytic conversion of rubber and plastic waste to hydrocarbon products which results in reduced levels of nitrogen and sulfur impurities in these products. The improvement comprises pyrolyzing the waste in the presence of at least about 1 weight percent of salts, based on the weight of the waste, preferably chloride or carbonate salts, of zinc or copper (I).This invention was made under contract with or subcontract thereunder of the Department of Energy Contract #DE-AC02-78-ER10049.

Abstract: Electrodepositable resins that do not require chromate corrosion inhibiting pigments and comprise (A) the at least partially neutralized reaction product of (1) an epoxy reactant having about two or more epoxy groups that are not linked by carboxy-ester moieties and (2) an amine reactant selected from mono and diamines containing primary or secondary amino groups and also being at least about 50 mole percent hydroxy amine, (B) water soluble or dispersible amino resin crosslinking agent are improved by incorporation of (C) a co-reactive flow control agent that comprises, for example, a polyepoxy copolymer having a molecular weight desirably between 1000-20,000. The co-reactive flow control agent, used at low levels, allows formation of smooth, non-tacky films exhibiting desirable corrosion resistant properties.
