Study Notes
Polymer Types and Properties
- Vulcanized rubber: Thermosetting polymer
- Common polymer bond: Covalent bond
- Cotton: Condensation polymer
- Polymer elasticity: Due to amorphous solid structure
- Diacid + diol reaction: Ester and water
- Polypropylene (PP): Thermoplastic polymer
- Polyethylene (PE): Thermoplastic polymer
- High PVA glass transition: Hydrogen bonding
- Thermoplastic polymer characteristics: Melts or deforms on heating; shaped; chains interact via intermolecular forces
- Low-density polyethylene (LDPE): Addition polymer
- Man-made polymers: Polypropylene, polyurethane, Teflon
- Natural polymers: Wood, silk, wool
- Vinyl monomer: Ethene
- Block copolymer: Side chains of one polymer attached to a backbone of a different polymer
- Addition polymerization requirement: Carbon-carbon double bond
- Nylon: Condensation polymer
- Polypropane forms: (Specific forms A, B, C, D are not defined in the context, so a detailed explanation can't be provided)
- Thermosetting polymer characteristics: Increased strength; chains tied by chemical bonds; heated to set structure; maintain shape, strong upon heating
- High-density polyethylene (HDPE): Higher volume than LDPE
- Phenylethene monomer: Not directly followed by any resulting polymer identification
- Condensation reaction products: Not directly detailed
- Strong polymer structure: Linear structure
- Polyethylene isomers: Symmetrical monomer
- Definition of polymer: A large molecule made by monomers
- Teflon application: Non-stick surfaces
- Plastic starting material: Petroleum or oil
- Isotactic polypropane form: (Specific form A, B, C, D is not defined, so a detailed explanation can't be provided)
- Condensation polymerization loss: Water
Polymerization Types
- Addition polymerization: Monomers with carbon-carbon double bonds join
- Condensation polymerization: Monomers join, releasing small molecules (e.g., water)
Other Polymer-Related Concepts
- Polymer structure: Linear, branched, ring
- Polymer isomerism: Isotactic, syndiotactic, atactic
- Polymer properties: Elasticity, strength, melting point, density, surface area, shape, and durability
