ACRYLIC COMPOSITION FROM TWO PARTS CONTAINING ABILITY TO CURE Russian patent published in 2017 - IPC C08L33/12 C08L51/00 C04B28/02 A61M5/178 A61L24/06 C08F265/06 C08F2/44 B05C17/00 

FIELD: chemistry.

SUBSTANCE: composition comprises the liquid first part stable at storage and the liquid second part stable at storage which react with each other upon mixing with the formation of cement which hardens. The composition further comprises an acrylic monomer component and an amount of an initiator component for polymerizing the monomer component. The monomer component and the initiator component are typically in the separate parts of the two parts of the composition, so that the monomer component is stable at storage. The liquid first part contains, in a liquid carrier, acrylic polymer particles obtained by emulsion polymerization. A method for the preparation of a curable, two-part acrylic composition is also described. The composition is particularly useful when used in a syringe or a compression seal gun having at least two cylinders. A solid cement composition of bone cement, obtained by curing the acrylic composition consisting of two parts is porous and permits controlled release of antibiotics and medicines into the surrounding bone and tissue.

EFFECT: low temperature of the exothermic effect during curing, the adhesion of the composition of bone cement that prevents, in particular, tissue necrosis, and the provision of the porous bone cement provides the cement mechanical properties matching the characteristics of the surrounding bone.
