The correct answer is A. Addition polymerization.
Addition polymerization is a type of polymerization in which monomers are linked together to form a polymer without the loss of any small molecules. The monomers in addition polymerization are typically unsaturated hydrocarbons, which means that they have double or triple bonds. When these monomers are heated or exposed to a catalyst, the double or triple bonds break and the monomers add together to form a polymer chain.
Vinyl chloride acetate is a type of addition polymer that is made by the polymerization of vinyl chloride and acetic acid. Vinyl chloride is a colorless, flammable gas that is used to make a variety of products, including PVC pipe, vinyl flooring, and vinyl gloves. Acetic acid is a colorless, pungent liquid that is used to make a variety of products, including vinegar, aspirin, and nail polish remover.
When vinyl chloride and acetic acid are heated together, they react to form vinyl chloride acetate. Vinyl chloride acetate is a white, solid that is used to make a variety of products, including adhesives, sealants, and coatings.
B. Condensation polymerization is a type of polymerization in which two or more monomers are linked together to form a polymer with the loss of a small molecule, such as water. The monomers in condensation polymerization are typically bifunctional or multifunctional, which means that they have two or more functional groups that can react with each other. When these monomers are heated or exposed to a catalyst, the functional groups react with each other to form a polymer chain and a small molecule is lost.
C. Co-polymerization is a type of polymerization in which two or more different monomers are linked together to form a polymer. The monomers in co-polymerization can be either homopolymers or copolymers. Homopolymers are polymers that are made from a single type of monomer, while copolymers are polymers that are made from two or more different types of monomers.
D. None of these is the correct answer.
