摘要:
ABC block copolymers on the basis of butadiene, isoprene and optionally styrene, are provided by a polymerization process wherein the resultant block copolymer comprises:about 40 to 75 wt % of a block A based on butadiene (uniformly distributed vinyl group content less than about 15 wt %),up to about 25 wt % of a block B based on butadiene and isoprene (vinyl content less than about 15 wt %) or based on butadiene (vinyl content more than about 75 wt %)about 20 to 55 wt % of a block C based on butadiene and isoprene (vinyl content more than about 75 wt %). The ABC block copolymers are useful for the production of tire treads.

摘要:
Preparations for the sealing of tires with punctures are proposed, which contain the latex of synthetic isoprene rubbers or the latex of natural rubber together with latexes of synthetic isoprene rubbers, acrylate rubbers and/or methacrylate rubbers. The sealing preparations can contain an adhesive resin compatible with the latexes from the group comprising polyvinyl esters, polyvinyl alcohol and/or polyvinyl pyrrolidone, and also a pigment, with natural rubber latex, synthetic rubber latexes or their mixtures being used as rubber latex. Furthermore, an apparatus is described for the sealing and pumping up of the tire using an airbag inflation charge and also tires with an integrated sealing preparation.
摘要:
The invention relates to a container for the sealing of tires with punctures, with which it is possible to first mix a liquid sealant and a filler when sealing is to take place, but to keep them separate during the prior storage. The container has a first chamber for filler and a second chamber for the liquid sealant. The chambers are fixedly or movably connected together and at least one of the chambers can be compressed. Between the chambers there is a partition wall, which consists at least in part of a rupturable member which is torn so that the liquid sealant and the filler mix before injection of the mixture into the tire via an outlet valve by compression of the chamber.
