Macromolecules
In this post, I am sharing the Class 12 Chemistry Notes Chapter 14 PDF for the students of FSC 2nd Year. The name of this chapter is Macromolecules. Students can download the 12th Chemistry Chapter 14 Notes in PDF format on their laptops or mobile. These Chemistry Notes are for the FSC Part 2 students of all boards working under the Punjab Board like Gujranwala Board, Lahore Board, Faisalabad Board, Multan Board, Rawalpindi Board, Sargodha Board, DG Khan Board, and Sahiwal Board. Here are the complete FSC 2nd Year Chemistry Notes PDFs of all chapters.
Introduction
The large-sized molecules are formed by the combination of small repeating units called monomers, which are called macromolecules or polymers. The idea of macromolecules was given by Staudinger in 1920. He proposed the long-chain formula for polystyrene rubber and polyoxymethylene.
Polymerization:
The process in which smaller molecules or monomers combine to form bigger molecules is called polymerization. The word poly means many and mer means unit or parts. Polymers are largely used in our daily life. Artificial fiber, Nylon, polyester, orlon, dacron, rubber, and plastic are all polymers. The world would be different without plastic or artificial fibers. The polymers have replaced the natural materials. For example, wood and cotton have been replaced by plastic and synthetic fibers. It is better or worse but we are living in a plastic society. If we see the things that are present in our room, we can say we cannot live without plastic. Many things like TV sets, telephone sets, electrical wires insulation cushions, mats, curtains, switches, plastic baskets, etc are all polymers.
