    Abstract: The present invention concerns a composition and method of using adipamides in polymer applications. The composition is a blend of multi-components comprising dicarboxylic acids and amines. Specifically, the composition comprises adipic acid and monoethanolamine. The composition can further comprise at least one of the following: amides, esters, antioxidants, waxes, metal soaps, copolymers, polyesters, or fillers. However, these components are not necessary, and the composition can be utilized without these components. The composition is typically prepared in a cold reactor, wherein nitrogen flow is started and the temperature is increased gradually to approximately 360° F. Further, the disclosed composition reduces viscosity in polymer products, aids in melt integrity and process extrusion and promotes better mold release than conventional additives.

  • Patent number: 7662226
    Abstract: A process of producing an asphalt concrete with enhanced performance is provided by utilizing a primer comprising uintahite and an augmenter. The primer is added to a hot aggregate with a surface temperature of at least 250 deg. F. prior to addition of an asphalt-derived base binder. The primer forms a primer interlayer between the hot aggregate and the base binder. As a result, the asphalt concrete has enhanced performance when compared with other asphalt concretes produced without a primer being added.

  • Patent number: 7153353
    Abstract: A carnuba silicone wax which does not contain free silicone oil. This wax is obtained by reacting a silicone compound having a substituent with reactivity to the hydroxyl group in natural carnuba wax, with this hydroxyl group. A carboxyl group may be introduced into the molecule by reacting this hydroxyl group with a cyclic acid anhydride, and a silicone compound having a group which can react directly with this carboxyl group is made to react. Alternatively, a hydrogen silicone may be hydrosilylated by a double bond introduced by reacting an epoxy compound having a double bond with this carboxyl group.
