(57) [Abstract] [Purpose] 5 to 3 having a diameter of 0.5 to 75 μm Elastomers reinforced with 0 parts by weight of chitosan particles, their products and their mixing method. Composition Chitosan is modified by oxygen-reactive groups or nitrogen-reactive groups, resulting in more reactive chitosan for elastomers. An economical method of incorporating finer chitosan particles into the elastomer matrix has also been shown. In this method, chitosan is dissolved in an acid, mixed with a coagulation liquid (for latex coagulation), and the chitosan / coagulation liquid mixture is mixed with a latex solution, resulting in an elastomer / chitosan composite. The elastomer / chitosan composite may be used as is, or it may be used as a masterbatch and mixed with more elastomer. |
