<p>A polydimethylsiloxane with initiator on surface which is formed by SiH bonds crosslinking and contains 0.01-1At% of 10-uncedenyl-2-bromo-2-methyl propionate on surface. The material is prepared by mixing polymer precursor, crosslinker, initiator having alkenyl terminal in a ratio of 10:1:4-0.01, and resting for 6-24 hours. The polydimethylsiloxane with initiator on surface provided by the present invention can be further modified to form a functional layer on surface by initiated surface polymerizing reaction, and then is used in biocompatible, organic solvent compatible and heat sensitive materials. A polydimethylsiloxane with surface universally, permanently, diversely and functionally modified is achieved by a simple and convenient method in this invention.</p> |
