  • Patent number: 6416704
    Abstract: The invention relates to nylon compositions having improved surface aesthetics while maintaining its physical properties and to a method for preparing molded articles of from such nylon compositions. The nylon composition is composed of a substantially uniform blend of nylon 6,6,6 copolymer of from about 65 to about 75 parts by weight of caprolactam and from about 25 to about 35 parts by weight of hexamethylenediamine and adipic acid in a 1:1 ratio; together with a second polyamide which is nylon 6 homopolymer. The first polyamide is present in the overall composition in an amount of from about 7 to about 20 weight percent and said second polyamide is present in the overall composition in an amount of from about 80 to about 83 weight percent. The nylon compositions are useful to create injection molded articles having a good surface appearance and good performance at a low cost.
