Chemical Reactions in Polymers:

Functional group reactions.

Ring formation reactions (in the polymer backbone).

Crosslinking reactions.

Block and graft copolymer formation.

Polymer degradation.

Natural Polymers: 

Polysaccharides of vegetal origin (cases): Cellulose, Amylose and Amylopectin. Polysaccharides of animal origin (cases): Chitin, Chitosan and Glycogen.

Modifications of cellulose (cases): Cellulose xanthate (viscose rayon textile fibres); Cellulose acetate (rayon acetate textile fibres); Cellulose nitrate (plastics, lacquers, explosives); Hydroxyethyl Cellulose (emulsifiers, shampoo thickeners).

Natural Rubber: from Gutta Percha tree (thermoplastic - trans-1,4-isoprene), from Hevea Brasiliensis tree and Guayule bush (elastomer - cis-1,4-isoprene)
