摘要
以3,5-二烯丙氧基苄溴作起始物,以3,5-二羟基苯甲醇为文化单体,以三-(对羟基苯基)甲烷作核,通过收敛法合成了三代端基分别含六、十二、二十四个烯丙基的三代树枝状聚醚大分子,产物进行了1H-NMR、13C-NMR、MS等表征.
olyether dendritic polymers of three generations with branch ends mobified by allyl groups were synthesized by convergent approaches. 3,5 -dihydroxybenzyl alco hol was used as branching monomer while tris (4' -hydroxyphenyl) methane as core of the polymers. Allyl group was introduced from the beginning of the procedures,i.e., 3, 5-diallyloxybenzyl bromide was used as starting materials. There were six,twelve and twenty-four allyl groups in the three polymers respectively. Dendrimers,were characterized by 1H -NMR, 13C-NMR and MS.
