Plastik yang dapat terbiodegradasi merupakan topik yang sangat menarik saat ini. Polimer sintetik seperti polistiren (PS) yang terdapat dalam plastik memiliki sifat tahan terhadap fotodegradasi maupun biodegradasi. Sifat inilah yang menimbulkan masalah lingkungan karena degradasi polistiren di alam sangat lambat. Oleh karena itu diperlukan suatu solusi yang dapat memecahkan masalah tersebut. Salah satu solusi yang menjanjikan untuk mengatasi masalah tersebut adalah membuat plastik yang dapat terbiodegradasi. Pada penelitian ini telah diisolasi polistiren dari limbah styrofoam, kemudian PS ini dimodifikasi melalui reaksi sulfonasi untuk mensubstitusi gugus sulfonat kedalam rantai polistiren hingga terbentuk polistiren tersulfonasi (PSS).
In recently year biodegradable plastics are very interesting topics. One of synthetic polymer used as row material for plastic is polystyrene (PS). Polystyrene has been made to have properties that are resistant to photo- and bio-degradation in environment. These properties can cause environmental problems because PS is difficult decomposed by microorganisms. The aim of the experiments is designed to improve the properties of PS as well as by blending with biodegradable polymers. In this work, polystyrene used was isolated from plastic waste of styrofoam and modified by sulfonation reaction to increase polarity of polystyrene, so that it can form homogenous polyblends with PCL that is one of synthetic biodegradable polymers.
