| 发明名称 | Polyamide sheet silicate compositions | ||
| 摘要 | The invention relates to polyamide sheet silicate compositions, containing an untreated clay mineral and a water-soluble polyamide, the concentration of the clay material being greater than 30% by weight. Furthermore the invention relates to nanocomposites which contain clay minerals distributed homogeneously in a water-insoluble thermoplastic matrix. These nanocomposites are produced by mixing the polyamide sheet silicate composition and a water-insoluble thermoplastic in the melt. | ||

| 主权项 | 1. Clay material, comprising: at least one sheet silicate; and at least one water-soluble polyamide, wherein the proportion of sheet silicate, relative to the entire clay material, is 30% by weight to 60% by weight, and wherein at least 10 g of the at least one water-soluble polyamide is completely soluble in 1000 g water at 23° C. and wherein the at least one water-soluble polyamide is a polycondensate obtained by polycondensation of: a) at least one aliphatic (including cycloaliphatic) and/or aromatic dicarboxylic acid with 6 to 36 C atoms; and b) at least one diamine selected from diethylene glycol diamine, triethylene glycol diamine, tetraoxahexadecane diamine, tetraethylene glycol diamine, and trioxatridecane diamine. | ||
