| 摘要 |
A new class of multi-ester coupling agents has been disclosed which have the general formula, (CH2=CH-CO2)n X, where X is a radical from a polyhydroxy compound having 2 to 6 hydroxyl groups, and n is an integer equal to the number of hydroxy groups in the polyhydroxy compound. These coupling agents undergo anionic polymerization through the acrylate unsaturation rather than anionic attack at the ester linkage.
