The number and weight averaged molecular weights were obtained at around 137,277 and 237,754g/mole. The melting point was observed at 32℃. The contact angle of water droplet on fabrics treated with the water repellent was 140~145° for cotton and polyester, and 125~130° for wool and nylon. Since the critical surface tension was estimated at 20.7mN/m, even though relatively not so strong as fluorinated water repellent, it is considered to be used as a good water repellent practically.
