Abstract

Liquocellulose particles containing up to 30% water are treated with a reactant of sulphur dioxide and/or hydrogen sulphide, and the resulting solid material heated under pressure for a time and at a temperature sufficient to combine chemically at least a portion of the reactant with the liquocellulose. During the reaction lignin is thought to be released to act as a binder. Steam is preferably present during reaction, supplying both heat and the water necessary for the hydrolysis of the liquocellulose. The product may be shaped, and depending on the plasticizer used, may be thermoplastic or thermosetting. The sulphur dioxide and/or hydrogen sulphide may be used in conjunction with additives which are exemplified. Specifications 925,523 and 925,524 are referred to.
