The influence of concentration of polyvinylpyrrolidon water solution with different molecular mass on the value of wetting angle with the use of underlayer of different nature was researched. The correlation of adhesion to cohesion work for all compositions was calculated.
The influence of low-molecular additives of different structure on the polyvinylpyrrolidone and hydroxyethyl compositions has been researched. The adhesive ability based on the contact angle compositions carried on linings of variable nature has been characterized. The effect of additives of different nature on the adhesive strength of the glue seam of polyvinylpyrrolidone containing compositions estimated by Dupre-Ung methodology has been studied.
