Claims
- 1. A rubber tube comprising, in order starting from the outside:
- (a) a rubber composition layer comprising a rubber component comprising a copolymer of 98 to 80% by weight of isobutylene and 2 to 20% by weight of a brominated para-methylstyrene with the degree of bromination of the copolymer being 10 to 80%,
- (b) a layer comprising an alkoxysilane compound of the formula: ##STR3## wherein each of R.sup.1 and R.sup.2 is a saturated or unsaturated monovalent hydrocarbon group or alkoxy group, and each of R.sup.3 and R.sup.4 is a saturated or unsaturated monovalent hydrocarbon group, and
- (c) a resinous material layer.
- 2. The rubber tube of claim 1 wherein said resinous material is a polyamide resin.
- 3. The rubber tube of claim 1 wherein said resinous material is disposed inside the rubber tube.
- 4. The rubber tube of claim 1, wherein a surface of said resinous material layer which is adjacent to the layer comprising the alkoxysilane compound has been modified with a low-temperature plasma treatment or a corona discharge treatment.
- 5. The rubber tube of claim 1, wherein, in component (a), the partially brominated copolymer of isobutylene and para-methylstyrene is 20 to 70% brominated.
- 6. The rubber tube of claim 1, wherein, in component (a), the para-methylstyrene is present in the copolymer in an amount of 5 to 10% by weight.
- 7. The rubber tube of claim 1, wherein the alkoxysilane compound is a compound selected from the group comprising
- methyltriethoxysilane,
- vinyltrimethoxysilane,
- phenyltrimethoxysilane,
- 3-aminopropyltrimethoxysilane,
- 3-chloropropyltrimethoxysilane,
- 3-mercaptopropyltimethoxysilane,
- 3-glycidoxypropyltrimethoxysilane,
- 3-methacryloxypropyltrimethoxysilane, and
- 3-ureidopropyltrimethoxysilane.
- 8. The rubber tube of claim 1, wherein the layer comprising the alkoxysilane compound has a thickness of 0.01 to 10 .mu.m.
