Abstract

Disclosed is a gas generating polymer compound that when irradiated with light or other radiation sources makes a solid to gas phase transition due to chemically catylized degradation, irradiative degradation or both. This provides a low cost, stable and easily manufactured means of gas production. Also disclosed are possible uses for the gas generator such as a low cost micro thruster.

Claims

1-29. -29. (canceled)

30. A micro thruster comprising a gas generating propellant, wherein the gas generating propellant comprises a gas generating polymer composition comprising:

a photo acid generator (A), and a polymer (B) that has a chain or branches susceptible to acidylic attack and converts to a gas when the chain is cleaved by acid formed from photo irradiation of the photo acid generator (A).

31. The micro thruster according to claim 30, wherein the polymer (B) is subject to photo degradation and converts to a gas under photo irradiation.

32. The micro thruster according to claim 30, wherein the gas generating polymer composition further comprises a polymer (C) that is subject to photo degradation and converts to a gas under photo irradiation.

33. The micro thruster according to claim 30, wherein the gas generating polymer composition further comprises a photo initiator.
