Abstract: The present invention relates to a method of preparing a fabric softener and to a fabric softener prepared thereby, and more particularly, to a method of preparing a fabric softener containing an esterquat by performing a two-step transesterification reaction on oil and tertiary hydroxyalkyl amine at a low temperature in a high vacuum state under specific conditions, and then quaternizing the resultant product. The method of preparing a fabric softener containing an esterquat according to the present invention can reduce the content of unconverted glyceride, glyceryl ester, or a mixture thereof, and can provide a fabric softener with excellent long-term stability.

Abstract: This invention provides a method for preparing a polymethylmethacrylate spherical bead and in particular, it provides a method for preparing a polymethylmethacrylate spherical bead characterized in that it is prepared by preparing polymethylmethacrylate by polymerizing methyl-methacrylate monomers, evaporating remaining methylmethacrylate monomers by raising temperature up to at least 100° C. after the polymerization reaction, and washing the polymethylmethacrylate with a mixed solvent of ethanol and water and vacuum drying them.
