INSULATING HEAT-RESISTANT PENETRATION COMPOUND AND A METHOD FOR PREPARATION THEREOF Russian patent published in 2007 - IPC C08L67/06 C08G63/56 H01B3/42 

FIELD: penetration materials.

SUBSTANCE: invention relates to insulating heat-resistant penetration compounds having improved physicochemical characteristics. Proposed compound comprises (wt parts): unsaturated nitrogen-containing polyester (37-39) prepared via polycondensation of unsaturated dicarboxylic acid anhydrides and polyatomic alcohols with N-(β-hydroxyethyl)-1,2-amidodicarboxylic acid; polymerizable diluent (36-128): polycarboxylic acid allyl esters and/or oligoetheracrylates; free-radical initiator (0.8-3.5); polymerization accelerator (0.4-1.6); inhibitor (0.04-0.6); and special additives (0.08-1.0). N-(β-Hydroxyethyl)-1,2-amidodicarboxylic acid is prepared by reaction of 2-aminoethanol and cyclic 1,2-dicarboxylic acid anhydrides. Method of preparing claimed compound is also described. To improve physicomechanical characteristics, additional addition of low-molecular weight epoxide resin in amount of 5-14.5 wt parts per 100 wt parts compound is possible.

EFFECT: reduced viscosity, environmental and fire safety at elevated heat resistance.
