Abstract RU 2135534 C1

FIELD: polymer materials. SUBSTANCE: gel composition contains styrene-alkylene-styrene block copolymer and at least 300 weight parts of liquid filler per 100 weight parts of copolymer, wherein indicated liquid ensures expansion and softening of polyalkylene blocks in block copolymer. Composition is distinguished by that styrene-alkylene-styrene block copolymer contains 20 to 100% of ethylenepropylene units based on total weight of polyalkylene blocks and liquid filler contains poly-alpha-olefin or its mixture with nonaromatic oil filler (90% of mixture). EFFECT: increased sedimentation resistance of gels at elevated temperatures due to elevated softening temperatures. 14 cl, 1 dwg, 1 tbl
