Preliminary 1H NMR studyon waterlogged wood strengthened with Klucel

Waterlogged woods from sea or lakes are very fragile because chemical, physical and biological decay. Wood artefacts, if directly dried in air, risk a structurally collapse and loss original form and dimension. The progressive substitution of water with suitable strengthening materials can preserve the characteristic of the wood finds. Among various natural and synthetic polymers suitable for this porpoise we have chosen aqueous solutions of Klucel (hydroxypropylcellulose), a polymer obtained from etherification of cellulose. This compound can interact with all the components of the wooden structure (cellulose, hemicellulose and lignin) and can cover the cavities by a protective and stabili…
