INSOLUBLE GAS-FILLED MICROSPHERES CONTAINING A HYDROPHOBIC BARRIER |
摘要 |
The present invention relates to a process for making insoluble gas-filled, pressure-resistant microspheres containing a liquid or solid hydrophobic barrier within the microsphere shell, and products of this process. This barrier serves to decrease the rate of gas exchange between the microsphere and the aqueous environment surrounding the microsphere and thus enhances resistance to pressure due to gas exchange.
