| 摘要 |
The present invention relates to plastics comprising a high molecular weight, sterically hindered amine, wherein the sterically hindered amine is at least one amine from the group consisting of I: oligomerized 2,2,4,4-tetramethyl-20(oxiranyl-methyl)-7-oxa-3,20-diazadispiro¢5.1.11.2!heneicosan-21-one, II: condensation product of 2-chloro-4,6-di(4-n-butylamino-1,2,2,6,6-pentamethylpiperidyl)-1,3,5-triazine and 1,2-bis(3-aminopropylamino)ethane, and III: condensation product of 1-hydroxyethyl-2,2,6,6-tetramethyl-4-hydroxypiperidine and succinic acid. These plastics exhibit a reduced rate of uptake of sulfur compounds. The invention further relates to shaped articles made from these plastics.
