  • Patent number: 4265663
    Abstract: This invention relates to liquid poly(alpha-olefins) in wax solutions or emulsions which when applied to surfaces (such as by way of illustration and not of limitation vinyl, leather, rubber, elastomers, natural and synthetic polymers, sealed and finished wood, painted or enameled metal such as automobile finishes, etc.) are capable of cleaning, preserving, renewing, restoring and improving the appearance, etc., thereof so as to yield a high gloss finish which is durable and has high resistance to water and detergent wash-off. The preferred embodiment contains the liquid poly(alpha-olefins) in conjunction with silicones and most preferably with metal salts such as zinc salts.

  • Patent number: 4224204
    Abstract: This invention relates to the use of hydrocarbon polymers for example of the type described in U.S. Pat. No. 4,060,569 to bind oil contained in waxes so that, in end use performance, the wax more closely equals fully refined wax. Among other things, the hydrocarbon polymer not only inhibits and/or prevents the oil in the wax from "sweating" or exuding to the surface but also hardens the wax. The hydrocarbon polymers can also be used to thicken oil to a paste or gel.
