Classify the following as addition and condensation polymers
Nylon 6,6, Buna-N,Buna-S,Polythene,Polystyrene,Polyvinyl chloride

Explanation

To classify the given polymers as addition or condensation polymers, we need to understand the definitions of each type:

1. **Addition Polymers**: These are formed by the addition of monomers with unsaturated bonds (like double bonds) without the loss of any small molecules (no by-products).

2. **Condensation Polymers**: These are formed by the reaction of monomers that results in the loss of small molecules, such as water or HCl, during the polymerization process.

Now, let's classify the given polymers:
