본 발명은 적어도 하나의 비수성 용매; 2,000 g/mol 내지 3,000,000 g/mol, 바람직하게는 10,000 내지 1,000,000 g/mol, 보다 바람직하게는 25,000 g/mol 내지 400,000 g/mol의 분자량을 갖는, 가교결합 반응을 겪을 수 있는 적어도 2개의 카복실 모이어티를 함유하는 다작용성 중합체와 폴리카보디이미드 또는 폴리아지리딘으로부터 선택되는 가교결합제의 반응으로부터 생성된 가교결합된 중합체를 포함하는 겔 매질에 관한 것이다. The present invention relates to a gel medium comprising at least one non-aqueous solvent; a crosslinked polymer resulting from the reaction of : a polyfunctional polymer containing at least two carboxyl moieties capable of undergoing crosslinking reactions, said polyfunctional polymer having a molecular weight from 2,000 g/mol to 3,000,000 g/mol, preferably from 10,000 to 1,000,000 g/mol, more preferably from 25,000 g/mol to 400,000 g/mol and a crosslinking agent chosen from a polycarbodiimide or a polyaziridine.
