Karen L. Wooley. The differences between the properties of crystalline organic materials of low molecular weight and the more indefinable class of materials referred to by Graham in as ‘colloids’ has long engaged the attention of chemists A polymer is a macromolecule (long molecules) built of small covalently bonded units called monomers (“mer” from the Greek word meros meaning part). H. WarsonTHE CONCEPT OF A POLYMERHistorical introduction. Polymers are very large molecules, or macromolecules, formed by the union of many smaller molecules. Synthetic vs. The macromolecules are bonded together by weak Van der Waals and hydrogen (secondary) bonds, or additional covalent cross-links Basic Concepts. Part I.

Polymers are very large molecules, or macromolecules, formed by the union of many smaller molecules. Polymers are high molecular weight compounds whose structures are made up of a large number of simple repeating units. These smaller units are termed monomers before they are converted into polymers. In fact, the word “polymer” has a Greek origin meaning “many members.” Natural polymers have been around since the early times in Planet Earth ContentsIntroduction and NomenclatureBrief Historical IntroductionDefinitionsNomenclature of PolymersNomenclature of Chain-Growth PolymersNomenclature of Step-Growth PolymersSteric Arrangement in Macromolecules INTRODUCTION.
