How is high density poly(ethene) characterized during its production?

High-density poly(ethene), or HDPE, is characterized during its production by less branching in the polymer chains, which results in a more linear structure. This linear arrangement allows the polymer chains to align closely alongside each other, leading to a denser and more crystalline material. The tighter packing of the chains contributes to HDPE's excellent strength and durability, making it suitable for various applications like bottles and containers.

The other options refer to different characteristics or types of polymer production. For example, random branching in polymer chains typically describes low-density poly(ethene) (LDPE), which has a more branched structure and is less rigid. Stronger crosslinks are more relevant to thermosetting plastics rather than HDPE, and while temperature control can affect polymerization processes, it does not specifically define the structural characteristics of HDPE.
