摘要

5886 taining 10 residue per cent lauroyl groups). For each nitrophenyl ester the rate is substantially greater with lauroylpolyethylenimine than with polymer containing no acyl group. Furthermore the trend in k is now markedly upward as the acyl group is increased from 2 to 12 carbons (see Table I). Compared to k for propyl- amine with nitrophenyl laurate, the corresponding k for lauroylpolyethylenimine is lo4 times greater. Such a comparison may not be fully appropriate if the low rate with ...
