Polymer
Poly = many
Mer = units
• Polymers are large molecules that has many units bonded together
• The individual units made up the polymer are called monomers

Man-made or Synthetic Polymers
Type 1: Addition polymers
• Made by addition reaction of monomers that have double bonds or triple bonds
![Page 6: Organic Chemistry POLYMERS. Polymer Poly = many Mer = units Polymers are large molecules that has many units bonded together The individual units made](https://reader035.vdocuments.mx/reader035/viewer/2022062716/56649dc55503460f94ab8b22/html5/thumbnails/6.jpg)
Properties of Addition Polymers
• Stable as the double bond converted to single bond
• Flexible, stretchable and mouldable thanks to lots of weak, intermolecular forces that hold the long polymer chain together

Plastic bag- How it’s made??? Made from a polymer
called polyethylene
• Take 1 million years to break down/ degrade a plastic bag

Super absorbent Polymer (Cont)
•H1. absorb up to 1,000 g of water per gram of polymer

POLYMER TIME! Making slime•Pour Elmer Glue to the mark in a plastic cup•Add equal volume of water to dissolve the glue•Add desire food colorant•Stir •Add prepared Borax solution DROPWISE until the slime is somewhat thicken•Don’t add too much Borax
