ABSTRACT:
The present invention provides a process for preparing a high water-containing elastomer medical catheter and a urinary catheter prepared by the process. The process is carried out by a) heating a mixture consisting of polyvinyl alcohol, water, sulfoxide and linear alkane, in a sealed vessel with agitating; b) pouring the resulting homogeneous fluid into a mould; c) solidifying the fluid by cooling; d) releasing the solidified fluid from the mould; and e) heat-treating the resulting medical catheter and washing with a polar organic solvent. The medical catheter and the urinary catheter of the present invention have excellent lubricity.
