POLYPROPYLENE AND PROPYLENES' COPOLYMERS WITH ETHYLENE |
| 摘要 |
Resistance against hot water and detergent solutions is achieved if the plastic material contains a combination of 0.1 to 0.5 percent by weight of derivative mixture of 2,2,6,6-tetramethylpiperidine with polymerization degree of 100 to 800 with bis-2-tert.butyl-4R-phenylpentaerytritoldiphosphite, where R is alkyl or aralkyl group, in weight ratio of 1:1 to 5:1.
