Abstract
A method for producing a tire filled with a (meth)acrylic hydrogel, the method comprises a) providing a mixture comprising at least one water-soluble (meth)acrylic compound, water and an initiator, and b) filling the mixture in a tire in which the mixture polymerizes to form the (meth)acrylic hydrogel. The tire filling material is suitable for producing flat proof tires, enables fast and controlled cure and is insensitive towards dosage errors. Moreover, the tire filling material is environmental friendly and cost effective.

A method for producing a tire filled with a (meth)acrylic hydrogel, the method comprises
- a) providing a mixture comprising at least one water-soluble (meth)acrylic compound, water and an initiator, and
- b) filling the mixture in the tire in which the mixture polymerizes to form the (meth)acrylic hydrogel.
A tire filled with a (meth)acrylic hydrogel, wherein the (meth)acrylic hydrogel consists of:
- (i) (meth)acrylic polymers containing repeating units having pendant groups, each pendant group being independently a carboxylate group or a carboxylate ester group,
- (ii) water, and
- (iii) optionally at least one component selected from the group consisting of an initiator, an accelerator, an antifreezing agent, an inhibitor, a diluent, and a filler.
