I am trying to find a hydrophilic polymer that sublimes in vacuum (~ 10-7 torr).
Can anyone help me or tell me where i could find one?

A hydrophilic polymer that sublimes in vacuum is a type of polymer that has a strong affinity for water and can transition from a solid to a gas state without going through a liquid phase when exposed to low pressure environments.
This type of polymer is commonly used in vacuum chambers to create a controlled environment for studying the behavior and properties of materials in low pressure conditions. It can also be used as a coating or film to protect sensitive materials from exposure to moisture during vacuum processes.
One major advantage is its ability to maintain a dry environment in vacuum chambers, which is crucial for many scientific experiments and processes. It also has a high water absorption capacity, making it useful for removing water vapor from the air in vacuum systems.
One limitation is that it can only be used in vacuum environments, so it may not be suitable for all applications. Additionally, the sublimation process can be affected by factors such as temperature and pressure, so careful control is necessary for accurate results.
The main difference is its ability to transition directly from a solid to a gas state without going through a liquid phase, which is unique to this type of polymer. It also has a strong affinity for water, making it particularly useful for applications involving moisture control.
