Abstract:
A composition which comprises as a main component a mixture comprising:(A) a polyvinyl ether having a kinematic viscosity in a range of 3 to 50 mm2/s at 100Â° C. in an amount exceeding 40% by weight and of 99.1% by weight or less and (B) a polyoxyalkylene glycol having a kinematic viscosity in a range of 3 to 50 mm2/s at 100Â° C. in an amount of 0.1% by weight or more and less than 40% by weight, â€ƒwherein the polyoxyalkylene glycol is a compound represented by general formula (I): R1â€”[(OR2)mâ€”OR3]nâ€ƒâ€ƒ(I) â€ƒwherein R1 represents hydrogen atom, an alkyl group having 1 to 3 carbon atoms, or an acyl group having 2 to 10 carbon atoms; R2 represents an alkylene group having 2 to 4 carbon atoms; R3 represents hydrogen atom, an alkyl group having 1 to 3 carbon atoms or an acyl group having 2 to 10 carbon atoms; n represents an integer of 1 to 6; and m represents numbers giving an average value of numbers represented by mÃ—n in a range of 6 to 80.
