Methacrylated chitosan CHIMA



CHIMA is a methacrylated derivative of chitosan. The precursor of CHIMA is chitosan, the second most common natural polysaccharide after cellulose, composed of a deacetylated part (beta-[1,4]- d-glucosamine) and an acetylated part (N-aceyl-d-glucosamine), obtained by partial deacetylation of chitin. It has been widely used in product design as a scaffold promoting cell adhesion. Metacrylation enables rapid, stable crosslinking of the material under UV/VIS light in the presence of a photoinitiator. CHIMA can be advantageously used as a blend with other methacrylates. We use 1HNMR analysis to measure the degree of metacrylation.
