PVA는 수용성을 가지며 유기용매와는 잘 섞이지 않음을 확인할 수 있다.
* FT-IR spectrum of PVA
* 합성한 PVA의 IR 그래프
- 제조한 PVA를 가지고 IR 분석을 거친 결과, 3400~3280cm-1의 범위에서 peaks가 나타났다. 이를 통해 PVA 안에 -OH(Hydroxy group)이 존재함

emulsions. Emulsion polymerization depend on the kind of monomer, quality of water, kind of initiator, amount of surfactant, temperature and other reaction parameters.
In the first, we had to make the solution definitely. Put the water, initiator, monomer(styrene) and also surfactant into the flask.

te of polymerization and allow for the separation and purification of the product styrene.
Improving conversion and so reducing the amount of ethylbenzene that must be separated is the chief impetus for researching alternative routes to styrene. Other than the POSM process, none of these routes like
