Which of the following is an addition polymer?
Correct answer: C. Acrylic resins
- A. Polyester
- B. Epoxy resins
- C. Acrylic resins
- D. Polyamides
Explanation
In 1929, WH Carothers suggested classification of polymers based upon the way polymers are formed. In condensation polymerization, the monomers are joined together with the removal of a small molecule. They are generally ionic in nature. In addition polymerisation, the monomers are joined together without any removal and they have double bonds.Acrylic resins are used in the manufacture of plastics, paints for car industry and water based weather resistant paints. The common monomers are methyl methacrylate, acrylic acid and acrylonitrile. Each of these have double bonds where the monomers link together to form large chains of addition polymers. Therefore, option C is the correct answer.Structures of the monomers are shown below:(Source: PCTB book 2 page 272)

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
