To reduce costs and obtain excellent performance, acrylic modified lignin sulfonate instead of butyl methacrylate stearyl methacrylate was prepared to oil absorption resin. And 1, 4-butylene glycol dimethacrylate as a crosslinking agent, 2,2’-azo-bis-(2-methylpropionitrile) as the initiator, with butyl acrylate to product the high lignin oil-absorbing resin, selected the best scheme for preparing by the orthogonal method, and the different concentrations of lignin and the best resin properties determined by SEM and its oil absorption test. Experimental results show that the resin has the high oil absorption properties,the maximum absorption of 20 times, and the suction speed is fast that 90min to reach saturation; It also has other characteristics,such as inexpensive cost, lightweight, easy recycling and disposal, reusable and so on.

The differential microemulsion polymerization method was used to prepare the latex nanoparticles at different amount of monomer. The monomer mixture consists different amount of butyl methacrylate (BMA) that was varied from 5.7 g to 9.7 g. Thin film of latex nanoparticles was prepared using the spin coating method and has been dried at 100°C for 5 minutes. The particle sizes of latex nanoparticles were characterized using Zetasizer nanoseries and the structural properties of the samples was studied using Atomic Force Microscopy (AFM). As the BMA amount increased, the particle sizes of latex nanoparticles has found to decrease from 69.66 nm to 31.16 nm and the roughness has detected to reduce from 3.78 nm to 2.63 nm. We have found that the BMA content in the polymerization has sensitively effect the particle sizes and the structural properties of the latex nanoparticles.

Abstract A nitroxide (2,2,6,6-tetramethylpiperidin-1-oxyl, TEMPO) mediated polymerization method was applied to the graft polymerization of styrene (ST)/ n-butyl methacrylate (BMA) to isotactic polypropylene (PP). PP peroxides produced by γ-irradiation in air were used as macroinitiator for grafting. The molecular characteristics of grafted and free poly(ST-r-BMA) chains were analysed by gel permeation chromatography, NMR and IR measurements. The molecular weight of grafted poly(ST-r-BMA) cleaved from PP was slightly higher than that of free poly(ST-r-BMA) generated simultaneously in the reaction system. Polydispersities of these polymers were narrow, indicating that grafting proceeded in a living fashion. The incorporated amount of BMA into grafted poly(ST-r-BMA) was smaller than that of free poly(ST-r-BMA). It is considered that the local concentration of BMA around propagating ends of graft poly(ST-r-BMA) was lower than that around free poly(ST-r-BMA) because PP cannot be dissolved in BMA monomer but in ST monomer at the polymerization temperature.

Fried food is convenient for many people due to its pleasant texture and taste. On the other hand, it comes with the risk of high oil absorption which might lead to certain health problems. Resistant starch (RS) has been known to have a functionality of reducing oil absorption. Three different types of banana: Kepok (Musa paradisiaca formatypica), Raja Bulu (Musa paradisiaca L.) and Ambon (Musa paradisiaca L. var sapientum) were evaluated on its performance when utilized as source of resistant starch especially on their application in reducing oil absorption in fried food. Tempeh was used as the food model. Banana starch (RS2) was isolated through water alkaline extraction process, continued with modification process through three repeated cycles of autoclaving-cooling process to obtain the RS3. RS3 was added into the batter coating formulation at three substitution ratios (10%, 30% and 50%) and then used to coat tempeh before frying. Evaluation of resistant starch in batter and battered productwas conducted on the following parameters: fat content, water retention capacity (WRC), coating pick up and sensory analysis. The result of this study revealed that Raja Bulu showed the most effective result on reducing oil absorption in the food tested. In the three bananas used, the ratio of 50% performed best in coating pick up (highest), WRC (highest) and fat content(lowest) parameters, but not significantly different with the 30% ratio. In terms of sensory acceptance, using Raja Bulu as the selected banana type, 30% of substitution ratio was significantly more preferable by the panelists in crispness, oiliness, and overall acceptance attributes compared to control and other substitution ratios.
