METHOD OF OBTAINING ADHESIVE COMPOSITIONS FOR STICKY POLYVINYL CHLORIDE TAPES, WHICH CONTAINS HYDROXYLATED 1,2-POLYBUTADIENES Russian patent published in 2014 - IPC C09J127/22 C09J7/02 C09J193/04 

FIELD: chemistry.

SUBSTANCE: glue composition includes perchlorovinyl resin, plasticiser and adhesion-increasing additive. Composition additionally contains hydroxylated 1,2-polybutadiene or hydroxylated syndiotactic 1,2-polybutadiene in quantity from 1 to 15 wt.p.; hydroxylated 1,2-polybutadiene with average weight molecular weight from 8000 to 12000 being applied. Degree of hydroxylation in hydroxylated 1,2-polybutadiene consistitutes from 2 to 27%.

EFFECT: increased adhesion of sticky PVC-tape to metal surface.
