초록

탄소섬유강화 복합재료의 계면효과에 영향을 미치는 표면개질제의 합성과 분리를 목적으로 high density polyethylene(HDPE)에 acrylamide(AAm)를 inverse emulsion graft중합을 하여 생성되는 HDPE-g-PAAm를 toluene에 가용인 것과 불용인 것으로 분류하여, 그 생성비율 및 PE conversion에 미치는 중합조건의 영향을 검토하고, 생성되는 graft polymer(GP) 총량에 미치는 영향도 검토하였다. 생성된 GP는 graft된 PAAm(g-PAAm)의 함량이 적은 비수분산성(toluene에 가용인 것)과 함량이 많은 수분산성(toluene에 불용인 것)으로 분리되었으며, 두 종류의 GP의 생성비율은 사용한 AAm의 수용액의 농도에 크게 영향을 받았으며, PE conversion 및 GP총생산량은 교반속도가 어느 한계값(본 실험의 경우 160rpm)이상에서 급격히 감소함을 알 수 있었다.

Two types of coupling agents were used for the surface modification in high density polyethylene(HDPE)/carbon fiber composite. Toluene-soluble and water-dispersible HDPE-g-polyacrylamide(PAAm) graft polymers(GP) were simultaneously synthesized by the inverse emulsion graft polymerization method and the mutual separation of the respective components was made in the present study. Here, the influences of various polymerization conditions on the production ratio of two types of GP's, the PE conversion, and the total amount of the graft polymers obtained has been investigated. From this study it was revealed that the production ratio of the GP's was greatly affected by the concentration of AAm aqueous solution used, and that both the PE conversion and the total amount of GP's produced decreased abruptly beyond 160 rpm of the stirring speed in the present case.
