Abstract

An amphiphilic polymer, an amphiphilic polymer manufacturing method, use of an amphiphilic polymer as a contact lens material, and a contact lens material including the same are provided. The amphiphilic polymer includes amino-conjugated mono-HEMA (mHEMA-NH 2 ) and amphiphilic chitosan bonded to the same. The amphiphilic polymer manufacturing method includes providing a mHEMA-NH 2 , providing an amphiphilic chitosan, and bonding the mHEMA-NH 2 to the amphiphilic chitosan.

Claims (14)

1. An amphiphilic polymer, comprising:

amino-conjugated mono-HEMA (mHEMA-NH 2 ); and

amphiphilic chitosan bonded to the mHEMA-NH 2 ,

wherein the amphiphilic polymer has having the following structure:

2. A contact lens material, comprising the amphiphilic polymer according to claim 1 .

3. An amphiphilic polymer manufacturing method for manufacturing the amphiphilic polymer of claim 1 , including:

(S 1000 ) providing amino-conjugated mono-HEMA (mHEMA-NH 2 );

(S 2000 ) providing amphiphilic chitosan; and

(S 3000 ) bonding the mHEMA-NH 2 to the amphiphilic chitosan.

4. The method according to claim 3 , comprising a step of reacting ethylene diamine, potassium carbonate, and mHEMA-4-toluenesulfonyl-grafted (mHEMA-Ts) to obtain the mHEMA-NH 2 .

5. The method according to claim 4 , comprising a step of reacting mHEMA with 4-toluenesulfonyl chloride (TsCl) to obtain the HEMA-4-toluenesulfonyl-grafted.

6. The method according to claim 5 , further comprising during reaction of the mHEMA with 4-toluenesulfonyl chloride, using 4-dimethylaminopyridine (DMAP) as a catalyst.

7. The method according to claim 3 , wherein the step S 3000 comprises using 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) as a catalyst.

8. The method according to claim 3 , wherein the step S 3000 comprises using N-hydroxysuccinimide (NHS) as a catalyst.
