| titleOfInvention | METHOD FOR PRODUCING COLLOID-FREE, UNPROTECTED POLYVINYL ACETALLOUS SOLUTIONS |
| abstract | The invention relates to a process for the preparation of Polyvinylbutyralloesungen with a degree of acetalization of 0.40 to 0.80 mol / mol. The dissolved polyvinyl butyrals are recovered by direct reaction of a polyvinyl alcohol with butyraldehyde in an alkanol. The solutions free from colloidal components and free of optical turbidity are obtained by adding 3 to 3 kg / kg in the presence of anhydrous urea in a concentration of 310 to 910 and adding the urea only at the time when the polyvinyl alcohol completely dissolves {polyvinyl alcohol; alkanol; butyraldehyde; acetylation; polyvinyl butyral; butanol; Urea; colloids; True environments; Polyvinyl butyral solution, free of turbidity; acetalization} |
