Interpretation: The structure of polymer formed from p-dioxanone is to be drawn.
Concept introduction: The repeated bonding of monomer units lead to the formation of polymer. They are mainly synthesized through condensation or addition reaction of monomer units. However, two or more monomers units that have different structure leads to the formation of copolymer.

- 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.arrow_forwardIf we are talking about viscoelastic modulus or viscoelastic relaxation modulus in polymers, indicate the correct option.(A). It reports the variation of elastic behavior as a function of time.(B). It is only useful for defining its glass transition temperature.(C). It only allows us to define the polymer degradation temperature.(D). Neither option is correct.arrow_forwardWhen natural light falls perpendicularly on a material A, it has a reflectivity of 0.813%.
