Solution and Explanation

Toys are typically made using various polymers that are widely utilized. 
Some commonly used polymers include: 

  1. Polyethylene (PE): This polymer is widely used in toy manufacturing due to its versatility, durability, and low cost. It comes in various forms, such as low-density polyethylene (LDPE) and high-density polyethylene (HDPE). 
  2. Polypropylene (PP): PP is another popular polymer used for toy production. It offers good impact resistance, flexibility, and chemical resistance. It is commonly used for toys that require strength and durability. 
  3. Polyvinyl chloride (PVC): PVC is a widely used polymer for making toys, particularly for products like dolls, action figures, and inflatable toys. It is known for its flexibility, low cost, and ease of processing. 
  4. Polystyrene (PS): PS is commonly used for toys like building blocks, model kits, and disposable toy items. It is lightweight, rigid, and can be easily molded or formed. 
  5. Polyethylene terephthalate (PET): PET is commonly used for making transparent or clear plastic toys, such as water bottles, toy packaging, and certain figurines. 
  6. Acrylonitrile butadiene styrene (ABS): ABS is a versatile and impact-resistant polymer used in the production of toys with complex shapes, such as building blocks, action figures, and remote-controlled vehicles.

Types of Polymerization Reactions

Polymerization is a chemical reaction in which a large number of monomer molecules combine to produce a polymer. A polymerization can yield macromolecules with a linear or branching structure. They can also take the form of a three-dimensional complicated network. 

Types of Polymerisation

Polymerization reactions are divided into two groups, namely, Addition polymerization (chain reaction) and condensation reaction (step reaction). 

  • Addition Polymerisation: As the name denotes, we can see the addition of monomers to form a polymer, twice the number or even more than that. Here, we can either select monomers of the same species or of different species. When we choose the single species monomers for the polymerization, the product thus formed is known as homopolymer (for example polythene used to make bags). When we use two different species for additional polymerization, the polymer would be known as copolymer (for example, Buna-S and Buna-N).
  • Condensation Polymerisation: In the condensation polymerisation, we can find elimination of compounds like HCL, water, alcohol etc...; while the monomers condense during the reaction process. This reaction happens between tri-function and bi-function monomer units and results in the formation of polymers like nylon.
