Poly(3-hydroxybutanoic acid), a biodegradable polyester, is an insoluble, opaque ma-terial that is difficult to process into shapes. In contrast, the copolymer of 3-hydroxy-butanoic acid and 3-hydroxyoctanoic acid is a transparent polymer that shows goodsolubility in a number of organic solvents. Explain the difference in properties betweenthese two polymers in terms of their structure.Poly(3-hydroxybutanoic acid)Poly(3-hydroxybutanoic acid-3-hydroxyoctanoic acid) copolymer

Draw the structure of the polymer that results from anionic polymerization of p-trichloromethylstyrene (CCl3C6H4CH =CH2) using ethylene oxide as the electrophile to terminate the chain.
In reference to cloth or fiber, the term acetate usually means cellulose acetate, a semisynthetic polymer made by treating cellulose with acetic anhydride. Cellulose acetate is spun into yarn by dissolving it in acetone or methylene chloride and forcing the solution through spinnerets into warm air, where the solvent evaporates. An organic chemistry student wore a long-sleeved acetate blouse to the laboratory. She was rinsing a warm separatory funnel with acetone when the pressure rose and blew out the stopper. Her right arm was drenched with acetone, but she was unconcerned because acetone is not very toxic. About ten minutes later, the right arm of the student’s blouse disintegrated into a pile of white fluff, leaving her with a ragged short sleeve and the tatters of a cuff remaining around her wrist. Explain how a substance as innocuous as acetone ruined the student’s blouse.
