Abstract

Целулозата, обработена по този метод, може да намери приложение в хранителната промишленост. По метода към влакнестата целулозна маса се прибавя хидрофобен полимер, по-специално полистирол, като се образува разтвор от полимера в органичен разтворител, който се прибавя към целулозата. Получената по този метод целулоза е с по-голяма йоннообменна способност и може също така да бъде регенерирана. Преди регенериране е за предпочитане целулозата да се обработи с алкален разтвор. 13 претенцииCellulose processed by this method can be used in the food industry. In the method, a hydrophobic polymer, particularly polystyrene, is added to the fibrous cellulose pulp by forming a solution of the polymer in an organic solvent which is added to the cellulose. The cellulose obtained by this method has a greater ion exchange capacity and can also be regenerated. Before regeneration, it is preferable to treat the pulp with an alkaline solution. 13 claims
