POLYMER COMPOSITION Russian patent published in 2004 - IPC

FIELD: polymer materials.

SUBSTANCE: invention relates to radiation-resistant hold-cure polymer composition consisted of 100 wt parts of resin constituent based on 4,4'-isopropylidenediphenol resin, 12-60 wt parts of amine hardener, and 30-400 wt parts of filler. Resin constituent additionally contains aliphatic epoxide resin and aliphatic alcohol at their weight ratio between 90:5:5 and 30:25:45, respectively. Amine hardener is reaction product of aromatic di- or polyamine, salicylic acid, benzyl alcohol, and furfurol at their weight ratio between 82:2:8:2 and 44:10:30:16, respectively.

EFFECT: enabled insulation of high-radioactive refuses under shock, vibration, and temperature variation (between -60 and +120^оС) conditions.
