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.
