Method of producing and the use of microfibrillated paper
- 2009
-
Patent (populärvet., debatt m.m.)abstract
- The present invention relates to a method of producing a cellulose based paper, the paper itself and the use thereof where the paper exhibits enhanced mechanical properties. The method involves providing a suspension of well dispersed modified cellulose at a low concentration. The properties and the chemical structure of the paper make it suitable for in vivo applications such as implant material.

Method for prepn. of biological degradability regenerative cellulose waterproof film and cellulose products
- 1998
-
Patent (populärvet., debatt m.m.)abstract
- A process for preparing water-proof regenerated cellulose film and water-proof cellulose products freatures use of biodegradable water-proof paint which is composed of pre-polymer of polyurthane, nitrocellulose, SO1-17 liquid, ethyl acetate and less N, N -dimethyl ethanolamine. Its technological steps include coating the surface of regenerated fibre film or cellulose product with and solidifying at 70-90 deg. C for 1-5 min. Obtained products have obviousely improved water-proof nature and tension strength over than 350 kg/sq. cm after immersed in water. The water vapour penetrating it is 0.004-0.005 g.sq. cm. d. It is fully biodegradable.

Copolymer, modified polymer carbohydrate material, modified buld polymer, composite material, and methods of preparation
- 2006
-
Patent (populärvet., debatt m.m.)abstract
- The present invention relates to a novel group of copolymers comprising a soluble carbohydrate polymer (SCP), which typically is a non-starch carbohydrate, and a macromolecule covalently attached to the SCP. The macromolecule may e.g. be a hydrophobic copolymer, a polyelectrolyte polymer or a biodegradable polymer. The present invention furthermore relates to a method of preparing the copolymer, products comprising the copolymer, and to methods of preparing the products comprising the copolymer. The products comprising a copolymer are for example a polymeric carbohydrate material (PCM) modified by attachment of a copolymer, and a composite material comprising the modified PCM.

Process for preparing hydroxy ethyl cellulose
- 2002
-
Patent (populärvet., debatt m.m.)abstract
- The present invention discloses a new method for cellulose in NaOH / Urea homogeneous hydroxyethyl Preparation hydroxyethylcellulose. The method of the cellulose is completely dissolved in 6wt% sodium hydroxide / 4wt% aqueous solution of urea, and 2-chloroethanol with hydroxyethyl cellulose homogeneous reaction in the aqueous solution used successfully prepared water-soluble hydroxyethyl cellulose. No significant degradation of cellulose occurs in the course of the reaction. This is a new process for the preparation of hydroxyethyl cellulose, low cost, non-polluting, and high product purity, good uniformity.
