Abstract: A telechelic macromer is disclosed having (meth)acrylic end-groups and a core. The macromer defined by Formula 1 comprises a core Y (Formulas 2 to 9) that is linked to (meth)acrylic groups by urethane, ester or anhydride bonds and has iodine value ranging from 5 to 75. The method involves a chemical reaction carried out in solvent, ranging 6-24 hours, wherein the precursor of a core (Formulas 2 and 3) reacts in two stages with compounds forming urethane bonds, or wherein the precursor of a core (Formulas 4 to 8) reacts in one stage with compounds forming ester bonds, or wherein the precursor of a core defined by Formula 9 reacts in one stage with compounds forming anhydride bonds. The urethane, ester and anhydride moieties comprise groups capable of free radical polymerization isolating the final product by evaporation. The composition disclosed provides the macromer, a photoinitiator and possibly a reactive diluent.

Abstract: A method for the producing of an agent for the removal of dissolved phosphorus compounds from water, relying on the formation of the biopolymer metal compound system which is characterized by that, the natural plant fibers are subjected to the activation, subsequently the activated natural plant fibers are coated with biopolymer or derivatives thereof with the ionic character. The natural plant fibers are coated with at least one water-soluble polyvalent metal compound before or after coating the natural plant fibers with biopolymer or derivatives thereof with the ionic character. Such modified natural plant fibers form a composite fibrous material in the form of biopolymer hydrogel support crosslinked in the presence of water-soluble polyvalent metal compound support on the warp from natural fiber.

Abstract: The present invention relates to an application of a composition containing telechelic macromer and photoinitiator for producing implant for hernia repair. The macromer structure is defined by Formula 1. The macromer bears (meth)acrylic end-groups and comprises a core Y defined by Formulas 2 to 9, that is linked by urethane, ester or anhydride bonds to the (meth)acrylic groups. The iodine value of the macromer is from 5 to 75. The composition according to the present invention can be shaped at room temperature and at 37° C. and is capable of undergoing liquid-to-solid transition upon irradiation with low intensity light. Upon irradiation with light the composition gains desired physicochemical properties and turns into an elastic solid. The implant for hernia repair serves for closing the hernia opening and for enhancing mechanical strength of abdominal wall.
