METHOD OF PRODUCING POLYPHENYLSILSESQUIOXANE POLYDIORGANOSILOXANE BLOCK COPOLYMER |
| 摘要 |
FIELD: chemistry. ^ SUBSTANCE: disclosed is a method which involves heterofunctional polycondensation of polyphenylsilsesquioxane and polydiorganosiloxane of formula (I), where n=100-640, in an organic solvent medium in the presence of diethylhydroxyl amine at temperature 110-120C and weight ratio of polyphenylsilsesquioxane to polydiorganosiloxane ranging from 10:90 to 50:50. ^ EFFECT: method enables to obtain block copolymers, cold curing vulcanisates of which, along with good physical and mechanical properties, have good oil-and-petrol resistance. ^ 1 cl, 1 tbl, 4 ex |
