초록

Styrene과 divinylbenzene의 몰비와 용매의 체적비를 변화시키면서 poly(styrene-co-divinyl-benzene) macrogel을 합성하여 합성한 macrogel의 중량 팽윤도, 가교점간 분자량등을 측정하였다. 또한, macrogel을 9∼84시간 동안 초음파 분해하였다. 초음파 분해하여 얻어진 macrogel의 특성을 gel permeation chromatography및 점도측정을 통하여 고찰하였다. 초음파 분해시간이 증가할수록 고 가교밀도를 갖는 작은 크기의 입자에 비해 저 가교밀도를 갖는 큰 크기의 입자들이 우선적으로 절단되었고, GPC profile이 저 분자량 쪽으로 이동하였으며, 본 실험조건의 절단 한계치인 elution count 19.43(M_w=1.60×10⁵)에 수렴하였다.

Poly(styrene-co-divinylbenzene) macrogels were synthesized by varing the volume fractions of solvents and mole ratios of monomers. Weight swelling degree and molecular weight per crosslinked unit of the macrogels were determined. The macrogels were degraded by ultrasonic degradation for 9∼ 84 hours, and the obtained macrogels were characterized by gel permeation chromatography and viscometry. As ultrasonic degradation time increased, largo size particles with low crosslinked density were degraded preferentially, compared with small size particles having high crosslinked density. GPC profiles of the obtained macrogels were shifted to low molecular weight region and approached elution count 19.43(M_w=1.60×10⁵) with degradation time.
