The present invention describes a composition comprising a diene-based rubber and at least one cyclo-aliphatic epoxide-based polyether or polyglycol ether. The present invention also describes a composition comprising at least one extending oil and at least one cyclo-aliphatic epoxide-based polyether or polyglycol ether, wherein the at least one extending oil is selected from the group consisting of an aromatic oil, an aliphatic oil, a naphthenic oil, and mixtures thereof.

A method for increasing the monomer conversion in a redox initiated emulsion polymerization has been discovered. The method comprises adding a composition comprising an effective amount of a substituted phenol to the polymerization medium. In this manner, high monomer conversion is obtained and the product has low gel contents and a low amount or no crosslinking.

Increased monomer conversion in emulsion polymerization

A swivel chair of the type comprising a seat which is supported at an elevated position above a base for swiveling motion relative to the base, and which has a foot support disposed between the base and seat for aiding a user of the chair to ascend to the elevated seat, is provided with clamping elements that are responsive to foot pressure applied to the foot support for preventing swiveling motion of the seat relative to the base when such foot pressure in excess of a predetermined amount is applied. The clamping elements preferably comprise an inclined surface on a bracket that pivotally supports the foot support, and a wedge-shaped element that is disposed between the inclined surface and the pillar of the swivel chair for axial displacement in response to pivotal motion of the foot support resulting from the application of foot pressure thereto.

Elevated swivel chair having a movable foot support for locking the

An improved actuator button apparatus is disclosed for use in adjustable chairs. The manually actuable button is pressed through an aperture in the chair frame and then moved along a pivoted lever until the button reaches a retention position. Movement of the lever activates or deactivates a chair positioning linkage within the housing.

Actuator button apparatus for adjustable chairs

An improved inclinable chair structure is disclosed in which a laterally movable lever (6), mounted on the seat frame (4) for easy access from the front, moves along a laterally disposed cam surface (2, 2a, 2b) which is rigidly secured to the chair base (1).
