Method for producing two-function polylactide scaffolds intended for cell cultures

摘要

The scope of the notification is the production of two -function polylactic rock for cell -grown crops,consisting of:that the polylactide is placed in the solvent and mixed to dissolve the polymer completely,methanol is then added to the solution and mixed to obtain a homogeneous solution,then add n -butanol or n -propanol and continue to mix to obtain a homogeneous solution,then pour the solution onto the floor and dry. Pure molecular weight polylactide Mn 25 -40 kg /mol and centre D 0,51 -1%content are used,chloroform is used as a polylactide solvent,dichloromethane or tetrahydrofuran,and the concentration of polyamide in the solvent solution is 6 -15%weight,with adhesive 350 -50 cP,and methanol and n -butanol or n -propanol are used in relation to 1:5 to a polylactide solvent,and after addition of n -butanol or n -propanol, the mixture is heated to a temperature 31 -38oC,and drying is carried out at the relative humidity 30 -40% and in the inert gas flow.
