Polymerization

Polymerization is grouping micro mulecules become (monomer) menjadi macro molecules (Polymer). Based of making synthetic polymer is bonding at natural polymer.

Reaction of making synthetic polymer consist of two part. They are:

• Adition Polymerization

Chain reaction from monomers that have a double bonding at least . Chain reaction from monomers has identity with broken of double bonding.

Example:

ETENE → POLIETENE

VINIL CLORIDA → POLYVINIL CLORIDA (PVC)

• Condensation Polymerization

Reaction that happen at molecules whice have similar or different two functional groups at least, like: -OH; - COOH; - NH2. This reaction is accompanied with release micro molecule like: H2O, NH3, CH3OH

Example : polyester (dacron), polyamida (nylon 66), etc.
