摘要:
Dispersion of filler(s) in polymeric compositions are improved by the use of a polymer-filler coupling compound, Q—A—B, wherein Q comprises a dipolar nitrogen-containing moiety that can form a 1,3 dipolar addition to an unsaturated carbon-carbon bond; B is an oxazoline, thiazoline, alkoxysilane or allyltin moiety, and A is a linking atom or group that forms a bridge between Q and B.
摘要:
A method for preparing an innerliner of a pneumatic tire and adhering an electronic monitoring device to the innerliner includes the step of providing a patch having a cover and a layer of uncured rubber. The patch is placed at a selected area of the innerliner of a green tire before the green tire is cured. At least a portion of the patch is removed after the tire is cured to provide a prepared area at the selected area of the tire. The electronic monitoring device is then adhered to the prepared area.
摘要:
A method for monitoring various physical conditions of pneumatic tires, and to a tire including a monitoring device. More particularly, the invention relates to a method of monitoring tires which uses an active, self-powered programmable electronic device which is installed in or on the interior surface of a pneumatic tire or on a tire rim. This device can be used for monitoring, storing and telemetering information such as temperature, pressure, tire rotations and/or other operating conditions of a pneumatic tire, along with tire identification information. The device can be activated by externally transmitted radio frequency waves and in response, the device compares or transmits information and provides a warning in the event a preselected limit is exceeded.

摘要:
An anionic polymerization initiator comprising the reaction product of a functionalizing agent selected from the group consisting of substituted aldimines, ketimines and secondary amines and, an organolithium compound. Elastomeric polymers prepared with these initiators have functional sites incorporated at the initiator end of the polymer chain and provide vulcanizable rubber compounds exhibiting reduced hysteresis. Articles such as tires, produced with low hysteresis elastomeric polymers have lower rolling resistance. Methods are also provided for preparing the initiators, functionalized polymers and vulcanizable elastomeric compounds having reduced hysteresis.
摘要:
A process is provided for preparing a terminally functionalized polymer from a living polymer obtained by anionic polymerization of a diene monomer or mixture of a diene monomer and a vinyl aromatic hydrocarbon monomer which comprises reacting the living polymer with a compound having the formula: ##STR1## wherein R.sub.1 and R.sub.2 are selected from the group consisting of H, alkyl, cycloalkyl, aryl, dialkylaminoaryl, aralkyl, and aprotic O, N and S- containing alkyl, cycloalkyl, aryl and aralkyl groups; wherein R.sub.3 is selected from the group consisting of alkyl, cycloalkyl, aryl, dialkylaminoaryl, aralkyl, and aprotic O, N and S- containing alkyl, cycloalkyl, aryl and aralkyl groups; with the proviso that at least one of the R.sub.1, R.sub.2 and R.sub.3 groups must be a dialkylaminoaryl group and that not all of the R.sub.1, R.sub.2 and R.sub.3 groups can be aryl groups.The resultant terminally functionalized polymer has reduced hysteresis properties and may be utilized to prepare elastomer compositions and tire treads having reduced rolling resistance.
摘要:
An elastomer article capable of being pressurized has a hollow extending therethrough. An elastomer free grid, generally in the form of a woven fabric, is located on the interior of the article in the vicinity of the hollow and prevents the same from being removed therefrom. An elastomer patch is utilized therewith.
摘要:
The invention provides a monitoring device and tire combination wherein an antenna is mounted to the tire in a location spaced from the monitoring device. In one embodiment, the antenna may be mounted to the tire sidewall outside the body cords of the tire. The antenna may be mounted on the outer surface of the sidewall or embedded within the body of the sidewall. The antenna is connected to the monitoring device with a connector. The connector may be electrically coupled to the monitoring device or may be connected to the monitoring device with a plug and socket connection. When the antenna is outside the body cord, the connector may extend from the antenna through the bead filler, over the top of the turn up, or under the bead ring.
