ACRYLIC POLYMER COAGULATES
摘要:
The present invention provides a multilayered acrylic polymer coagulate characterized in that the coagulate has a bulk density of 0.3 to 0.6 g/cm3 and a median diameter of 50 to 400 μm and contains particles having a particle diameter of 75 or less in a proportion of 50% or less, and the amount of alkali metal and alkaline earth metal contained in the coagulate satisfies the following formula (1): Σ(N/a)×(120−Tg)≤100   (1) wherein N represents the amount of alkali metal and alkaline earth metal contained in the coagulate (mmol/kg); Tg represents the glass transition temperature (° C.) of the acetone-soluble matter of the coagulate; and a represents the valency of the alkali metal and alkaline earth metal contained in the coagulate.
