APPENDIX A: POLYMER MAKEDOWN PROCEDURES 



0.1-Percent Solution of Drys 



1. Measure 100 mg of dry polymer. 



2. Add slowly to 40 ml of tap water being agitated on magnetic 

 stirrer. 



3. Mix 30 min minimum to dissolve. 



4. Add 60 ml of tap water to make total volume of 100 ml. 



5. Mix 5 min and observe to ensure solution is completely mixed. 



0.5-Percent Solution of Liquids 



1. Measure 99.5 ml of tap water. 



2. Add 0.5 ml of polymer with a syringe. 



3. Mix 5 min on a magnetic stirrer. 



0.1-Percent Solution of Emulsions 



1. Measure 0.5 ml of emulsion polymer with a syringe. 



2. Add to 99.5 ml of tap water being agitated on a magnetic stirrer. 



3. Mix for 5 min at high speed. Result is 0.5-percent solution. 



4. Take 20 ml of the 0.5-percent polymer solution, place in a 150-ml 

 jar, and mix 30 min minimum. 



5. Add 80 ml of tap water and mix an additional 5 min on a magnetic 

 stirrer.
