POLYMER FOR BLOOD SEPARATING MEDIA AND BLOOD SEPARATING MEDIUM COMPOSITIONS

摘要

A polymer for blood separating media consisting of a (meth)acrylic ester polymer made from a raw material comprising one or more (meth)acrylic ester monomers, which polymer has a specific gravity of 1.025 to 1.060, a weight-average molecular weight of 3000 to 50000, a viscosity of 10 to 300Pa·S at 25ºC, and an oxygen content of 10 to 22%. It is preferable that a (meth)acrylic ester having C<SUB>6-10</SUB> cyclic alkyl be contained as part of the (meth)acrylic ester monomers still preferably in an amount of 5 to 50% by mass based on the ester monomers. The cyclic alkyl is preferably cyclohexyl or isobonyl.
