Abstract: A composition useful as a catalyst in solution polymerization comprises (1) a barium, calcium and/or strontium alcoholate, (2) an organoaluminum compound and (3) an organomagnesium compound. (2) and (3) may be used as a complex with (1). The compositions can be used to polymerize ethylenically unsaturated monomers like butadiene, butadiene and styrene, and isoprene and heterocyclic monomers like oxiranes, thiiranes, siloxanes, thiatanes and lactams. The catalyst composition can produce polybutadienes and butadiene-styrene copolymers having a trans-1,4 content as high as 90%. The non-terminating features of the polymerization of this invention permit the preparation of functionally terminated butadiene based polymers and block polymers containing sufficient amounts of trans-1,4 butadiene units to crystallize.

Abstract: Divinyl benzene and/or diisopropenyl benzene in hydrocarbon solvent is added over a period of time at low temperature to a hydrocarbon solvent containing a C.sub.2-20 normal, secondary or tertiary alkyl or cycloalkyl lithium compound and a tertiary alkylamine having 2-4 carbon atoms prepared at low temperature to provide an initiator having an average of from 4 to 9 C-Li sites and a VPO Mn of from about 750 to 4,000. These initiators are useful in polymerizing dienes and vinyl monomers to provide star polymers having an average of from about 4 to 9 arms or branches. These star polymers among other things are useful low profile or low shrink additives for FRPs, e.g., glass fiber reinforced plastics.

Abstract: A hay rake tine assembly is disclosed in which the tines are attached to a mounting plate by an elastomeric body which buckles upon the application of excessive force to the tines. The buckling decreases the spring rate of the body and avoids excessive tension and compression forces, which may result in failure of the metal-rubber bonds. The body also includes a clearance for the deflection of the tine. The assembly also includes an engagement between the tine and the mounting plates so that the tine will not drop in the event of rubber failure.

Abstract: An aramid reinforcing element is treated with a cold gas plasma of air, N.sub.2, He, Ne or Ar or mixture thereof at up to 300 watts power for a few seconds to several minutes to improve its adhesion to rubber compounds.

Abstract: A method of making radial pneumatic tires substantially reduces or eliminates sidewall indentations in the inflated tire. A plurality of cuts is made in one end of each layer of ply fabric where the end of the ply fabric overlaps the other end to form a splice which results in the generally annular shape of the ply layer. The cuts extend in a direction generally transverse to the end edge and preferably have a length which is approximately the same as the width of the overlap of the cut edge with the other edge. The cuts prevent overtensioning of the ply cords, which otherwise result in sidewall indentations.

Abstract: A pneumatic tire having a pocket filled with lubricant attached to the inner sidewall of the tire having a puncture sealant surrounded by an O-ring built into the inside wall of the pocket. The puncture sealant allows lubricant to be injected into the pocket by use of a syringe and eliminates the need for subsequent sealing of the pocket and leakage of lubricant from the pocket.

Abstract: An apparatus and method are provided for applying an envelope-type wrapping to tire bead rings. The apparatus and method are particularly useful when the wrapping material is to be applied directly over a lubricant coating on the bead ring. The apparatus includes a radially expansible drum, and an inflatable bladder that covers the drum and is interposed, along with the wrapping material, between the bead ring and the drum. According to the method of the invention, the bladder is inflated and rolled over in a desired sequence of steps to apply an envelope wrapping to the bead ring.

Abstract: Polyamides such as nylon-6 type polyamides are prepared by the reaction or copolymerization of a major amount by weight of a lactam and a minor amount by weight of a graft copolymer of maleic anhydride on a low molecular weight liquid conjugated diene polymer or copolymer or of a copolymer of a conjugated diene and a monovinyl aryl monomer or a nitrile. For example, a graft of maleic anhydride on liquid butadiene/acrylonitrile copolymer is copolymerized with epsilon-caprolactam using an anionic lactam polymerization catalyst (a lactamate salt) like the reaction product of ethyl magnesium bromide and epsilon-caprolactam. The present invention may be useful in a RIM (Reaction Injection Molding) process. The resulting polyamides have improved impact strength and water resistance. They can be used to make automobile and truck bodies and parts.

Abstract: A U-shaped polymeric strip to be mounted on a body flange adjacent a vehicle door opening has an improved sealing structure for preventing moisture from seeping around the end of the body flange inside the U-shaped strip. The sealing structure is located at the inside of the base of the U-shaped strip and comprises a polymeric material, such as sponge rubber, that is relatively soft compared to the relatively hard polymeric material of the main portions of the strip. The relatively soft polymeric material of the sealing structure is formed into two parts, each having a convex outer surface, separated by a slot that extends lengthwise of the strip and receives the edge of the body flange.

Abstract: Humid aged adhesion of rubber containing a phenol formaldehyde resin bonded directly to bright steel cord is improved by coating the bright steel cord with an amino functional organo silane.

Abstract: An SMC (FRP) molding is coated with a minimum amount of an IMC composition by skewing one of the mold halves during the initial IMC molding cycle to effect a scissoring action, the fulcrum being at or about the IMC injection point or placement to spread or wipe the IMC over the surface of the SMC part and then effecting at least substantial parallelism of the mold halves during the remaining IMC cycle of coating and curing the IMC.
