- the materials are mixed by conventional means known to those skilled in the art, in a single step or in stages.
- the carbon black is added in a different stage from zinc oxide and other cure activators and accelerators.
- antioxidants, antiozonants and processing materials are added in a stage after the carbon black has been processed with the elastomeric composition, and zinc oxide is added at a final stage to maximize compound modulus.
- a two to three (or more) stage processing sequence is preferred. Additional stages may involve incremental additions of filler and processing oils.
- compositions may be vulcanized by subjecting them using heat or radiation according to any conventional vulcanization process.
- the vulcanization is conducted at a temperature ranging from about 100°C to about 250°C in one embodiment, from 150°C to 200°C in another embodiment, for about 1 to 150 minutes.
- Suitable elastomeric compositions for such articles as tire innerliners may be prepared by using conventional mixing techniques including, e.g., kneading, roller milling, extruder mixing, internal mixing (such as with a BanburyTM or BrabenderTM mixer) etc.
- the sequence of mixing and temperatures employed are well known to the skilled rubber compounder, the objective being the dispersion of fillers, activators and curatives in the polymer matrix without excessive heat buildup.
- a useful mixing procedure utilizes a BanburyTM mixer in which the copolymer rubber, carbon black and plasticizer are added and the composition mixed for the desired time or to a particular temperature to achieve adequate dispersion of the ingredients.
- the rubber and a portion of the carbon black (e.g., one-third to two thirds) is mixed for a short time (e.g., about 1 to 3 minutes) followed by the remainder of the carbon black and oil. Mixing is continued for about 5 to 10 minutes at high rotor speed during which time the mixed components reach a temperature of about 140°C. Following cooling, the components are mixed in a second step on a rubber mill or in a BanburyTM mixer during which the curing agent and optional accelerators, are thoroughly and uniformly dispersed at relatively low temperature, e.g., about 80°C to about 105°C, to avoid premature curing of the composition. Variations in mixing will be readily apparent to those skilled in the art and the present invention is not limited to any specific mixing procedure. The mixing is performed to disperse all components of the composition thoroughly and uniformly.
- An innerliner stock is then prepared by calendering the compounded rubber composition into sheet material having a thickness of roughly 40 to 80 mil gauge and cutting the sheet material into strips of appropriate width and length for innerliner applications.
- the sheet stock at this stage of the manufacturing process is a sticky, uncured mass and is therefore subject to deformation and tearing as a consequence of handling and cutting operations associated with tire construction.
- the innerliner is then ready for use as an element in the construction of a pneumatic tire.
- the pneumatic tire is composed of a layered laminate comprising an outer surface which includes the tread and sidewall elements, an intermediate carcass layer which comprises a number of plies containing tire reinforcing fibers, (e.g., rayon, polyester, nylon or metal fibers) embedded in a rubbery matrix and an innerliner layer which is laminated to the inner surface of the carcass layer.
- Tires are normally built on a tire forming drum using the layers described above. After the uncured tire has been built on the drum, the uncured tire is placed in a heated mold having an inflatable tire shaping bladder to shape it and heat it to vulcanization temperatures by methods well known in the art.
- Vulcanization temperatures generally range from about 100°C to about 250°C, more preferably from 150°C to 200°C, and times may range from about one minute to several hours, more preferably from about 5 to 30 minutes.
- Vulcanization of the assembled tire results in vulcanization of all elements of the tire assembly, i.e., the innerliner, the carcass and the outer tread/sidewall layers and enhances the adhesion between these elements, resulting in a cured, unitary tire from the multilayers.

- the halogenated rubber component of the present invention is mixed with the other components by first combining the rubber components and mixed in a BanburyTM blender for 30 seconds at about 90°C, at which time 3/4 of the carbon black is added. Then, after mixing for several minutes and reaching a temperature of about 1 10°C, all of the remaining ingredients (processing oils, etc.) except for the curing ingredients (ZnO, MBTS and sulfur) are then added and blended. The mixing is then stopped when the temperature reaches about 140°C, and allowed to cool to room temperature. Finally, the curing ingredients are added in a subsequent mixing step and blended in to form the compositions 1-13 of the present invention.
- Compositions 1 -4 (Table 3) exemplify the halogenated butyl rubber embodiment of the invention, wherein Composition 1 is a comparative example with no added polybutene processing oil, and Compositions 2 and 3 have 7 phr of the 2500 Mn polybutene processing oil, and Composition 4 has 7 phr of the 1300 Mn polybutene processing oil.

This occurs with little change in the Tg or brittleness values. In one embodiment, the Tg values of the inventive compositions is from -38°C to -34°C.
