Acylated derivatives of substituted piperazines and polymeric compositions stabilized thereby |
| abstract |
Acylated derivatives of substituted piperazines are stabilizers for synthetic polymeric materials normally subject to deterioration caused by ultraviolet light. The compounds are prepared by the acylation reaction between a substituted piperazine and a mono or di-acid halide, ester or isocyanate. Polymeric compositions containing these stabilizers may also contain a hindered phenolic compound. A typical embodiment is 15-stearoyl-7,15-diazadispiro[5,1,5,3]hexadecane. |
