| 摘要 |
The tendency of polyolefines, e.g. isotactic polypropylene and linear or low density polythene, to acquire charges of static electricity is reduced by incorporation of 0.01-5% of (1) an N-(hydroxyalkylated) fatty acid amide, (2) an alkylene oxide condensate of a fatty acid amide, (3) an alkylene oxide condensate of (1), or (4) a mixture of two or more compounds from classes (1) to (3), the fatty acid amide contains 6-22 C. atoms. The amide may be NN-di-(b -hydroxyethyl) lauramide or stearamide and may be incorporated into the molten polyolefine which is then shaped into fibres, films or mouldings. Specification 941,796 is referred to.
