본 발명은 중화된 펜던트 카르복실기(염) 및 펜던트 카르복실기를 함유하고, 반복 단위를 가짐을 특징으로 하는 혈액 및 기타 단백질 함유 용액의 흡수에 특히 적합한 중합체 조성물을 제공한다. 본 발명의 중합체 조성물은 중화된 펜던트 카르복실기 대 펜던트 카르복실기의 비율이 약 1:9 내지 약 9:11이고, 반복 단위 중 약 20몰% 이상이 중화된 펜던트 카르복실기 또는 펜던트 카르복실기로 이루어지며, 중화된 펜던트 카르복실기중 약 50% 이상이 칼륨 또는 리튬으로 중화되어 있음을 특징으로 한다. A polymeric composition specifically adapted to absorb blood and other proteinaceous fluids and having repeating units, said polymeric composition comprising pendant neutralized carboxyl groups (salts) and pendant carboxyl groups. The polymeric composition is characterized in that the ratio of pendant neutralized carboxyl groups to pendant carboxyl groups is within the range of from about 1:9 to about 9:11, at least about 20 mole percent of the repeating units comprise a pendant neutralized carboxyl group or a pendant carboxyl group, and at least about 50 percent of the pendant neutralized carboxyl groups have been neutralized with a potassium or lithium base.
