<p>PURPOSE:The titled composition low in swelling a plastic and suitable for electrical insulation, containing a specified aromatic monoolefin or diolefin. CONSTITUTION:The titled composition is obtained by mixing 5wt% or above aromatic monoolefin or diolefin containing a plurality of (non)condensed aromatic rings, represented by formula I -III [wherein R1 and R3 are each (cyclo)alkyl, or (cyclo)alkenyl, R2 is (cyclo)alkylene, or (cyclo)alkenylene, m and n are each >=0, and the total number of the aliphatical double bonds in all of the groups is 1 or 2] with a low-MW polymer (e.g., petroleum resin) and, optionally, a plasticizer compatible with said aromatic olefin (e.g., phthalate ester), a softener, and other resins. An electrical appliance or device such as a transformer or a capacitor is impregnated with the above composition, and it is cured by heating or the like.</p> |
