Polymerization of butadiene ( C H 2 = C H C H = C H 2 ) does not yield the same polymer as polymerization of ethylene( C H 2 = C H 2 ). a) How could we convert poly (butadiene) to poly (ethylene)? b) Predict the reactivity of poly (butadiene) with H B r .

Question

Speaking of composite materials, indicate the correct option:(A). Composite materials can only be: metal-polymer or polymer-polymer.(B). Composite materials can be made up of particles, but not fibers or sheets.(C). When the reinforcing particles are uniformly distributed in a composite material, there may be a greater tendency for it to have isotropic properties.(D). None of the above is correct.

Answer 1

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.
