Exercise 38

Cellulose acetate is a thermoplastic polymer of vegetable origin produced mainly from cellulose obtained from cotton: it is therefore a vegetable product not derived from petroleum. It is the ideal material to produce glass-like materials, for its workability and for the appearance of the finished product. Cellulose acetate is widely used because it is a tenacious material, with great resistance to impact and, when exposed to sunlight, does not discolor. Due to its versatility, it is produced in a wide range of transparent or translucent colours. Thanks to its chemical and mechanical characteristics, it is an extremely versatile material because it is heated and resolidified according to the needs of use.

Cellulose acetate has the following structure

If you have not already done so, download Avogadro for free and watch the tutorials if necessary.

Build with Avogadro the corresponding monomer and indicate how many and which are the chiral coals and what shape the ring structures have.
