| titleOfInvention | METHOD FOR PRODUCING COLLOID-FREE, UNMUTATED SOLUTIONS OF MODIFIED POLYVINYLBUTYRALES |
| abstract | The invention relates to a process for the preparation of modified Polyvinylbutyralloesungen with a degree of acetalization of 0.4 to 0.8 mol / mol. The dissolved, modified polyvinyl butyrals are obtained by direct reaction of a modified polyvinyl alcohol with butyraldehyde in an alkanol. The solutions free of colloidal components and having no optical turbidity are obtained by adding anhydrous urea in a concentration of from 310 3 to 9 3 kg / kg after the acetalization of the dispersed modified polyvinyl alcohol with butyraldehyde. {Modified polyvinyl alcohol; alkanol; butanol; butyraldehyde; acetylation; polyvinyl butyral; Urea; colloids; True environments; Polyvinyl butyral solution, free of turbidity; acetalization} |
