________ polymers result from polymerization reactions in which chain growth is accompanied by loss of a small molecule.
A) Addition
B) Condensation
C) Chain-growth
D) Latex
Condensation Polymers
Polymers formed by the condensation reaction, where two monomers react to produce a small molecule, such as water, along with the polymer.
Polymerization Reactions
Chemical reactions that join small molecules (monomers) together to form long chains or networks (polymers), which can be initiated by heat, light, or catalysts.
Chain Growth
The process in polymer chemistry where monomers add to a growing polymer chain one at a time, often characterized by a single active site.

Final Answer :
B
Explanation :
Condensation polymers result from polymerization reactions in which chain growth is accompanied by loss of a small molecule, such as water or alcohol. Examples include nylon, polyester, and polyurethane. Addition polymers, on the other hand, result from polymerization reactions in which monomers are added to the growing chain without the loss of any small molecules. Examples include polyethylene, polypropylene, and polystyrene. Chain-growth polymers and latex polymers are types of addition polymers.
