Abstract: An adhesive composition based on a monomeric ester of .alpha.-cyanacrylic acid and a modifying agent, viz. a monomeric fluorinated ether of dimethylvinylethynylcarbinol of the formula: ##STR1## wherein R is CH.sub.2 (CF.sub.2).sub.n H or CH.sub.2 (CF.sub.2).sub.n CF.sub.3 ; n=2 to 10.Owing to the addition of a monomeric fluorinated ether of dimethylvinylethynylcarbinol as a modifying agent into the adhesive composition, mechanical strength and water-resistant of the adhesive bond are improved. Thus, an ultimate shear strength of the adhesive bond produced from the adhesive composition according to the present invention after keeping in water for 10 days is equal to 119-185 kgf/cm.sup.2.

Abstract: A method of preparing blood-compatible sorbents for recovering exo- and endogenic poisons which comprises sorption of the blood-serum albumin on an anion exchange resin, cation exchange resin, activated carbon or a styrene and divinylbenzene copolymer with a specific surface area of at least 20 m.sup.2 /g. Thereafter, the sorbed albumin is subjected to polycondensation at a temperature ranging from 10.degree. to 90.degree. C. The method according to the present invention practically does not change the initial porous structure of the sorbents, thus ensuring sorption of such compounds as bilirubin, uric acid, creatinine, barbituric acid derivatives, potassium and ammonium ions, phenols, indoles, skatoles.
