Claims32
A golf ball comprising a core, a cover, and at least one water vapor barrier layer, wherein the water vapor barrier layer comprises at least one layer having a thickness of about 3 μm to about 10 μm formed from poly-para-xylylene and its derivatives having a structure:
- where
- A=a hydrogen or a group VIIA element;
- B=a hydrogen or a group VIIA element;
- X=a hydrogen or a group VIIA element;
- Y=a hydrogen or a group VIIA element;
- n=an integer between 1 and about 100;
- and
- A, B, X and Y may be the same or different from each other.
A golf ball comprising a core, a cover, at least one intermediate layer disposed between the core and the cover, and a first and second water vapor barrier layers disposed between the core and the cover, wherein the second water vapor barrier layer has a thickness of less than 0.030 inches and a water vapor transmission rate of less than about 0.80 g·mil/100 in2·24 h at 38° C. and 90% relative humidity, and the first water vapor barrier layer comprises at least one layer formed from poly-para-xylylene and its derivative having a structure:
- where
- A=a hydrogen or a group VIIA element;
- B=a hydrogen or a group VIIA element;
- X=a hydrogen or a group VIIA element;
- Y=a hydrogen or a group VIIA element;
- n=an integer between 1 and 100;
- and
- A, B, X and Y may be the same or different from each other.
A golf ball comprising a core having a center and at least one outer core layer, a cover, and a first and second water vapor barrier layers disposed between the center and the cover, wherein the second water vapor barrier layer has a thickness of less than 0.030 inches and a water vapor transmission rate of less than about 0.80 g·mil/100 in2·24 h at 38° C. and 90% relative humidity, and the first water vapor barrier layer comprises at least one layer formed from poly-para-xylylene and its derivatives having a structure:
- where
- A=a hydrogen or a group VIIA element;
- B=a hydrogen or a group VIIA element;
- X=a hydrogen or a group VIIA element;
- Y=a hydrogen or a group VIIA element;
- n=an integer between 1 and 100;
- and
- A, B, X and Y may be the same or different from each other.
