Zusammenfassung:	Chitosan Reinforced Tires and Method of Incorporating Chitosan into an Elastomer The invention relates to elastomers and articles reinforced with 5 to 30 phr Chitosan particles having a diameter of 0.5 to 75 microns. In an illustrated embodiment, the Chitosan may be modified with an oxygen reactive group or a nitrogen reactive group to make the Chitosan more reactive with an elastomer. Also provided is an economical method of incorporating very fine Chitosan particles into an elastomer matrix. In the method Chitosan is dissolved in an acid and mixed with a coagulating liquid (for coagulating latex), and the mixture of chitosan/coagulating liquid is mixed with a latex solution to provide an elastomer/chitosan composite. The elastomer/chitosan composite may be used as formed or it can be used as a masterbatch and mixed with more elastomer.
