МАКРОМОНОМЕР ДЛЯ ПОЛУЧЕНИЯ ДОБАВКИ К ЦЕМЕНТУ, СПОСОБ ЕГО ПОЛУЧЕНИЯ, ДОБАВКА К ЦЕМЕНТУ, ВКЛЮЧАЮЩАЯ ПОЛИКАРБОКСИЛЬНЫЙ СОПОЛИМЕР, ПОЛУЧЕННЫЙ ИЗ МАКРОМОНОМЕРА И СЛОИСТОГО ДВОЙНОГО ГИДРОКСИДА, И СПОСОБ ПОЛУЧЕНИЯ ДОБАВКИ К ЦЕМЕНТУ
Disclosed are a macromonomer for preparing a cement admixture and a method of preparing the same; a cement admixture comprising a polycarboxylic acid-based copolymer derived from the macromonomer and a layered double hydroxide; and a method of preparing the same. The polycarboxylic acid-based copolymer comprises (a) a structural unit derived from a macromonomer compound represented by Formula 1 below and (b) a structural unit derived from an acrylic monomer represented by Formula 4. The cement admixture has superior dispersibility, workability maintenance, and corrosion resistance. [Formula 1]:CH 2 =CR 1 -(CH 2 ) m -O-(CH 2 CH 2 O) n -OCO-R 2 -COOH [Formula 4]:CH 2 =CR 3 -COM 1
