Articles prepared from thermoplastic compositions, and method of preparing such articles

摘要

In some embodiments, a pressure vessel comprises a rounded container comprising a thermoplastic composition. The thermoplastic composition comprises a siloxane copolymer having a structural unit of the formula (11);
where x and y are integers representing the number of repeating units; and x is at least 1. The pressure vessel is configured to receive a fluid at an operating pressure of greater than or equal to 2 bar.

1. A pressure vessel comprising a rounded container comprising a thermoplastic composition, the thermoplastic composition comprising a siloxane copolymer having a structural unit of the following formulawhere x, y, and z are integers representing the number of repeating units; and x is at least 1; and
wherein the pressure vessel is configured to receive and contain a fluid at an operating pressure of greater than or equal to 2 bar, and wherein at least one of (i) the pressure vessel is configured to be constantly exposed to the operating pressure for greater than or equal to 3 years without leakage, and (ii) the pressure vessel is configured to be exposed to a constant pressure for greater than or equal to 3 years without failure as determined in accordance with ASTM D 1598.
