Erucamide has, to a great extent, replaced the use of oleamide because of its higher mp and higher heat resistance. These properties are desirable because of the higher operating temperatures of newer polymers. Various derivatives are discussed, such as N-stearyl erucamide, which has a still higher mp and greater thermal stability. This type of product is used principally as a slip additive, an antiblock agent, and for paper-coating compositions and water-proofing. Erucamide and some of its derivatives are approved for use in polymers at low concentration levels. At these levels, the material is effective without adversely affecting other physical characteristics of the polymer. A summary of the literature is presented, including a review of some of the patents. Size of the market also is discussed.
