Final answer:
A long, straight chain polyalkene refers to a polymer made up of repeating units of alkene monomers joined together in a straight chain without any branching. It has high density, strength, rigidity, and a higher melting point compared to branched polyalkenes.
Step-by-step explanation:
A long, straight chain polyalkene refers to a polymer made up of repeating units of alkene monomers joined together in a straight chain without any branching. One example of a long, straight chain polyalkene is polyethylene. Polyethylene is formed by the polymerization of ethylene (CH₂=CH₂) monomers.
The characteristics of a long, straight chain polyalkene include:
- High Density: These polymers have a high density due to the close packing of the polymer chains.
- Strength and Rigidness: The long, straight chain structure provides strength and rigidity to the polymer.
- Higher Melting Point: These polymers generally have a higher melting point compared to branched polyalkenes.
