Step-by-step solution

(A) Rubber is a natural polymer and possesses elastic properties. It is also termed as elastomeric polymer. Neoprene is a family of synthetic rubbers that are produced by the polymerization of chloroprene. So, the correct matching of elastomeric polymer is neoprene. (B) Polyesters are the polycondensation products of dicarboxylic acids and diols. Dacron or terylene is the best-known example of polyester. Dacron fibre is crease-resistant and is used in blending with cotton and wool fibres and also as glass reinforci
