Treatment agent composition null general expression for biodegradation Characteristic satisfactory

摘要

The present invention provides an oil fiber for synthetic fiber filaments which is free from smoke and sludge under high speed and high temperature, and has good lubricity, low static electricity, excellent winding property and good biodegradability. That is, the present invention is a synthetic resin composition composition characterized by containing a kind or two or more of a polyether polyester compound having a molecular weight represented by general formula: X - (a-b) n-a u2032 - y from 1000 to 20000. However, X and y are hydrogen peroxide / propylene oxide which has a hydrogen ratio and a molar ratio of ethylene oxide and propylene oxide to 9 / 1 to 1 The dodecar or random copolymerization residue, B is an aliphatic two basic acid residue represented by OC (CH2) mcoo, M is an integer of 1 to 4, and N is an integer of 1 to 3.
