が実用上望ましいことが知られている。Friction of general C-rubber [2] There are two types of friction: condensation friction and deformation friction.The former is mainly caused by shearing force that tries to separate the contact surfaces of two materials, and the latter tries to deform the contact surface layer. The main cause is the stress caused by It is known that for vulcanized rubber molded products used, for example, in golf club grips, it is practically desirable to have both high friction resistance.

2. Oligomers or polymers added to conventional rubber composition molding materials do not substantially have unsaturated bonds or functional groups such as halogen, hydroxyl, amino, imino, or carboxyl groups in the C2 molecules. It is important that the molecular weight is approximately 5. It has been found that a range of OO'O to so, o o o, preferably 6,000 to 30,000, is very effective.

く意外な発見であった。When this additive compound is added to a rubber composition for molding, there is no disadvantage of deterioration of the durability of the molded product, and the compound is slightly C-plume or oriented on the surface of the obtained molded product. In addition to improving wetting to the other object and increasing adhesive friction resistance, when the temperature of the contact area rises due to contact friction, the adhesiveness of the compound itself increases and the adhesive friction resistance increases. It promotes sex, and acts like a lubricant on vulcanized rubber that has a three-dimensional network structure.
It was a completely unexpected discovery that the deformation friction of the molded product could be effectively improved.

とを理解すべきである。Examples of such substances that are substantially free of unsaturated bonds and functional groups used in the present invention include a homopolymer of inbutylene or a combination of isobutylene and olefins such as ethylene and propylene. Mention may be made of copolymers. Moreover, the molecular weight of these polymers is 5
If it is less than ,000, the intermolecular cohesive force is weak, so the stability in the vulcanized rubber molded product is poor, and when blooming on the surface of the molded product, it is relatively easily displaced to other surfaces in contact with it. This is inconvenient, and if it exceeds 50,000, the softening temperature increases and the adhesiveness becomes poor, so adding it cannot be expected to significantly improve the adhesion friction of the vulcanized rubber molded product. This is not preferred because it has the disadvantage of reduced elasticity. Therefore, the molecular weight is 5,
Oligomers or polymers within the range of 000 to 50,000 are preferably used. It should be understood that the above molecular weight ranges are essentially (bi-average molecular weights) since these polymers are obtained in their manufacture as mixtures of various degrees of polymerization.

ない。By adding a small amount to the rubber composition, a commensurate increase in surface friction resistance can be imparted to the vulcanized rubber molded product, so the desired friction can be achieved depending on the type, size, usage conditions, etc. of the resulting molded product. The addition amount is appropriately selected depending on the resistance, and therefore the addition ratio is essentially C: Although not limited, it is usually 0.5 to 1 based on the rubber pellet molding material.
A range of 0% by weight is advantageously used in practice. If the amount is too large, the physical properties of the vulcanized rubber molded product will deteriorate, which is not preferable.

た。Using a device equipped with a glass plate whose angle can be adjusted freely and whose inclination angle with respect to the horizontal plane can be read, a vulcanized rubber sample plate is placed closely on the glass plate, and the outer diameter of the sample plate C2 is measured. A cylindrical reinforced hard glass tube (weight: about 6 g) with a length of 10 m and a length of 90 mm was placed perpendicular to the rotation axis of the plate, and the glass tube was moved downward by increasing the inclination angle of the glass plate. The angle at which the slide started was measured as the slip angle.
