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.

- 12. A way to produce a highly cross-linked polyester is to use glycerol. Alkyd resins are a polymer of this type. The polymer forms tough coatings when baked onto a surface and is in used in automobile paints and large appliances. Draw the structure of the polymer formed from the condensation of one glycerol and three phthalic acid molecules: H₂C-CH-CH₂ COH OH OH OH + сон Glycerol phthalic acidarrow_forwardPolychloroprene, commonly known as neoprene, is widely used in wetsuits and in rubber parts that must withstand exposure to gasoline or other solvents. What monomer is used to make this synthetic rubber?arrow_forwardPoly(lactic acid) (PLA) has received much recent attention because the lactic acid monomer [CH3CH(OH)COOH] from which it is made can be obtained from carbohydrates rather than petroleum. This makes PLA a more “environmentally friendly” polyester. (A further discussion of green polymer synthesis is presented in Chapter 28.) Draw the structure of PLA.arrow_forward
