- Abstract
- In this study, a grafted crosslinker, poly (succinimide) grafted methacrylate (PSI-g-MA) composed of poly (succinimide) as the hydrophobic backbone was prepared with various degree of substitution (DS) by introducing acrylic group. The polymers were synthesized by acid-catalyzed polycondensation reaction and DS was confirmed by 1H-NMR. Then, we prepared lipophilic gel for absorbing VOCs with silicone monomer and PSI-g-MA. The mechanical strength and the VOC absorbancy of the lipophilic gel were optimized by controlling the DS of PSI-g-MA with fixing the number of acrylic groups.
We analyzed the physical properties of lipophilic gels by measuring expansion ratio (S), swelling ratio (Q), and Young‘s modulus (E). Generally, swelling ratio of lipophilic gel decreases as mechanical strength increases. However, the lipophilic gel of this study can ‘independent control’ to control the mechanical strength with superior swelling ratio. In addition, lipophilic gels can be prepared to customized form for each type of VOCs. Overall, this lipophilic gel for absorbing VOCs prepared with grafted cross linker, PSI-g-MA, and silicon monomer would greatly used in various researches of organic chemical engineering, atmospheric engineering and environmental engineering.
