“…The increasing concentration of the monomer also increases the diffusion within the monomer in tapioca waste so that increasing the DC of the copolymer. Also, high monomer concentrations are suitable for forming complexes (receptor-contributor) between tapioca waste and its monomers [15]. Hence, the optimum monomer concentration from this study is 1:1 (100 % monomer addition, 20 g).…”

Nuclear technology can be applied not only as an energy (electricity) but also in industry as as an initiator on polymer reaction. Tapioca waste is used due to its biodegradability properties. Tapioca waste gel is formed by adding equal aquades ratio to waste weight. After gel formed, several concentrations of methyl methacrylate (w/w) is added to the gel then packed into 150 mL ampule. Using Co-60 gamma irradiation source, gel is irradiated at 5 kGy absorbed dose. Gel is extracted using acetone to get rid of sample from impurities. Glycerol as a plasticizer is added to the gel to increase polymer flexibility. Gel-Glycerol mixing is done at 60ºC, 250 rpm for one hour by adding aquadest. To analyze mechanical properties, firstly, we need to mold samples using pressurized-hot press machine. Film is formed to type 5 specimen (dog bone, astm d638-14). Specimen is tested by analyzing tensile strength characteristics. Fabrication of biodegradable plastic based packaging by using starch has an increasement of mechanical and thermal properties at 5 kGy absorbed dose. Methyl methacrylate 25, 50, 75, 100, 125 and 150% addition to the solution has 10-24 MPa tensile strength. Gel fraction has range between 88-100%. Even the lowest ratio of monomer addition can provide highest gel fraction to improve mechanical properties of tapioca waste.

“…The VAc polymer would eventually embed itself into the core of the graft polymer while the starch provided stabilization. Increase in starch:monomer ratio served to decrease all grafting performance as well as overall conversion [123,124,136].…”

On the Use of Starch in Emulsion Polymerizations

The substitution of petroleum-based synthetic polymers in latex formulations with sustainable and/or bio-based sources has increasingly been a focus of both academic and industrial research. Emulsion polymerization already provides a more sustainable way to produce polymers for coatings and adhesives, because it is a water-based process. It can be made even more attractive as a green alternative with the addition of starch, a renewable material that has proven to be extremely useful as a filler, stabilizer, property modifier and macromer. This work provides a critical review of attempts to modify and incorporate various types of starch in emulsion polymerizations. This review focusses on the method of initiation, grafting mechanisms, starch feeding strategies and the characterization methods. It provides a needed guide for those looking to modify starch in an emulsion polymerization to achieve a target grafting performance or to incorporate starch in latex formulations for the replacement of synthetic polymers.
