METHODS FOR PREPARING PHOSPHATE-ORGANIC COMPOUND, PHOSPHATE-ORGANIC COMPOUND AND DENTAL POLYMERIZING COMPOSITION BASED ON THEREOF Russian patent published in 2004 - IPC

FIELD: chemical technology, medicine, stomatology.

SUBSTANCE: invention relates to a phosphate-organic compound comprising a group able for polymerization. Invention describes a method for preparing monophosphate ester based on (meth)acrylic acid monoester involving: interaction of from 1 to 5 moles of diol comprising from 4 to 30 carbon atoms with 1 mole of (meth)acrylic acid in the content of (meth)acrylic acid from 60 to 90 mole%. This results to preparing the reaction mixture comprising (meth)acrylic acid monoester and diol and (meth)acrylic acid diester and diol wherein the molar ratio of (meth)acrylic acid monoester and diol to (meth)acrylic acid diester and diol is from 2 to 8; and interaction of formed (meth)acrylic acid monoester and diol with phosphorus oxychloride that results to preparing monophosphate ester based on (meth)acrylic acid monoester. Also, invention describes similar methods for preparing monophosphate ester based on (meth)acrylic acid monoester, monophosphate ester based on (meth)acrylic acid monoester and dental polymerizing composition based on thereof. Invention provides preparing compounds that elicit the enhanced stability in storage with expressed hydrophobicity in molecule that promotes to adhesion to teeth and longevity.

EFFECT: improved preparing methods, valuable properties of compound.
