This document provides an overview of a polymer science presentation for a class. It includes an introduction with presenter and recipient details. The main topics to be covered are the importance of polymers, their properties, classifications, and structures. Examples are given of polymer applications in medicine, consumer science, industry, and sports. Key polymer properties discussed are chain length, side groups, branching, and cross-linking. The classifications covered are based on origin, structure, molecular forces, and polymerization mode. The presentation concludes with thanks to the audience.

3. Today Is The Main Theme Of
Presentation:
• Study On Importance Of Polymer :
• Properties Of Polymer :
• Classification Of Polymer:
• And structure Of Polymer:

4. 1. MEDICINE: Many Biomaterials Especially Heart Valve.
Replacements And Blood Vessels, Are Made Of Polymers Like
Dacron, Teflon And Polyurethane.
2. CONSUMER SCIENCE: Plastic containers Of All Shapes And Sizes
Are Light Weight And Economically Less Expensive Than The More
Traditional Containers Clothing. Floor Coverings, Garbage Disposal
Bags. And Packaging Are Other Polymer Applications.
3. INDUSTRY: Automobile Parts, Windshields For Fighter Planes.
Pipes, Tanks, Packing Materials, Insulation, wood, Substitutes,
Adhesive, Matrix For Composites, And Elastomers Are All Polymer
Applications Used In The Industrial Market.
4. Sports: Playground Equipment, Various Balls Golf Clubs, Swimming
Pools and Protective Helmets Are Often Produced Rom Polymer.
STUDY ON IMPORTANCE OF POLYMER :

5. PROPERTIES OF POLYMERS:
The Physical Properties Of a Polymer, Such as
It’s Strength And Flexibility depend On :
□ chain Length- In General, The Longer The Chain The Stronger
The Polymer.
□ Side groups- Polar Side Groups Give stronger Attraction
Between Polymer Chains, Making The Polymer Stronger.
□ Branching- Straight, Un Branched Chains Can Pack Together
More Closely than highly branched Chains, Giving Polymers
That Are More Crystalline And Therefore Stronger.
□ Cross-linking- If polymer Chains Are Linked Together
Extensively By Covalent Bonds, The Polymer Is Harder And
More Difficult to Melt.
