*Plastik adalah polimer rantai+pan,ang dari atom yang mengikat satu samalain- $antai ini
membentuk banyak unit molekul berulang. atau /monomer/ hal tersebut merupakan pendapat
dari Septera 2013- Se,arahnya. tahun pada 120 4alla5e 6ume 7arothers. ahli kimia lulusan
"ni8ersitas 6ar8ard. mengembangkan nylon yang pada 9aktu itu disebut #iber ::- Pada tahun
1;0+an nylon. a5ryli5. polyethylene. dan polimer lainnya digunakan untuk menggantikan
bahan+bahan alami yang 9aktu itu semakin berkurang- ino8asi lainnya dalam plastik yaitu

!dalah sintetis aromatik polimer dibuat dari monomer stirena- Polystyrene bisa padat atau
berbusa- Tu,uan umum polystyrene ,elas. keras. dan agak rapuh- Ini adalah resin murah per
satuan berat- Ini adalah penghalang agak miskin oksigen dan uap air dan memiliki titik leleh
yang relati> rendah- Polystyrene merupakan salah satu yang paling banyak digunakan plastik.
skala produksi men,adi beberapa miliar kilogram per tahun- @)A Polystyrene bisa se5ara alami
transparan. tetapi dapat di9arnai dengan pe9arna- Penggunaan termasuk kemasan pelindung
seperti pengepakan ka5ang tanah dan 7( dan (aatkan untuk ekstrusi seperti dalam styro>oam. dan
,uga untuk molding dan 8akum. karena dapat dilemparkan ke dalam 5etakan dengan detail halus-
a. Sejarah
Polystyrene ditemukan pada tahun 1=3 oleh Eduard Simon. sebuah apotek dari 'erlin-
(ari storaC. resin dari Turki pohon s9eetgum Liquidambar orientalis, dia suling Dat berminyak.
monomer yang ia beri nama Styrol- 'eberapa hari kemudian. Simon menemukan bah9a Styrol
telah menebal. mungkin dari oksidasi. men,adi ,elly ia di,uluki Styrol oksida /StyroloCyd/-
%leh kimia9an 1=;) kelahiran amaika ohn 'uddle 'lyth dan kimia9an erman !gustus
4ilhelm 8on 6o>mann menun,ukkan bah9a trans>ormasi yang sama Styrol ter,adi dalam
ketiadaan oksigen- ereka disebut metastyrol substansi mereka- !nalisis kemudian
menun,ukkan bah9a itu adalah kimia identik dengan StyroloCyd- Pada 1=:: ar5elin 'erthelot
diidenti>ikasi dengan benar pembentukan metastyrol F StyroloCyd dari Styrol sebagai
polimerisasi proses- Sekitar =0 tahun kemudian disadari bah9a pemanasan Styrol memulai reaksi
berantai yang menghasilkan makromolekul. mengikuti tesis kimia organik erman 6ermann
