Los plásticos y los polímeros

Polymers, synthetic materials known for 150 years, are made from monomers derived from crude oil. The polymerization process forms long chains, creating plastics like polyethylene and polystyrene. Plastics' properties vary due to different monomers and chain arrangements. High-density polyethylene is dense and rigid, while branched polymers are flexible. Intermolecular forces and additives like crosslinking agents and plasticizers further alter polymer properties. These versatile materials are integral to modern life.

What role do crosslinking agents and plasticizers play in modifying the properties of polymers?
