Beschreibung
Zusammenfassung:	The invention provides a preparation method for a hydrophilic silicone macromer. The preparation method comprises the steps as follows: carrying out hydrosilation reaction on a silicon hydrogen bond of polysiloxane and a C=C double bond of a hydrophilic compound by a rhodium-containing catalyst to form a hydrophilic side chain with an amide functional group or a choline phosphate functional group in polysiloxane; and carrying out end capping reaction to form the hydrophilic silicone macromer.
