Pour light solvent and remove all the bubbles. Put a stopper and wipe run over solvent. Then, measure the weight, M2. 참고문헌 1 http://en.wikipedia.org/wiki/Polymer 2 http://en.wikipedia.org/wiki/File:Polypropylen.png 3 http://en.wikipedia.org/wiki/Density 4 http://www.google.co.kr/search?hl=ko&source=hp&biw=652&bih=472&q=specific+gravity-bottle+method&oq=specific+gravity-bottle+method&aq=f&aqi=&aql=&gs_sm=e&gs_upl=172l8625l0l8844l29l28l1l16l4l0l984l3094l0.1.4.0.2.0.1l8l0 5 http://www.infoplease.com/ce6/sci/A0861270.html 키워드 Density, Polymer, 고분자밀도측정, 고분자, Measurement
