FIELD: chemistry.
SUBSTANCE: invention relates to polyhydroxyethers used as film materials and protective adhesive coatings with high operational characteristics. Polyhydroxyether is a compound of formula
,
where m=50–140, based on 3,3-di(3,5-dibrom-4-oxyphenyl)phthalide (TBP) and 1-chloro-2,3-epoxypropane (ECG).
EFFECT: polyether has improved fire-resistance, strength, resistance to water and alkaline aggressive media, improved adhesion to aluminum.
