Process for production of modified cellulose pulp, pulp so obtained and use of biopolu00cdmero for production of celulse pulp.The present invention relates to a process for the production of refined pulp chemistry where biopolymers are added immediately before, during or after a bleaching stage, depending on the characteristics of the pulp and the process conditions used. The polymers according to the present invention are starch through an etherification reaction.This treatment results in a pulp having propridades different physical, chemical and mechanical aperfeiu00e7adas when compared with cellulose pulps obtained by traditional processes. The use of the said biopolymer modifies the relationships between properties of pulp and its application in the process of important papermaking advantageous.This differentiation increases the possibilities of use and also new applications, including for the replacement of the pulps produced from other sources of cellulose receive.In this way, the present invention also relates to a process for the preparation of paper, such as paper for printing, writing, decorative, or special type fabric, through the use of the pulp cellulose modified by the above process
