  • Halobutyl of improved green strength
    Patent number: 4256857
    Abstract: Bromobutyl rubber compounds of improved green strength are prepared by reacting bromobutyl rubber with selected amine compounds such that not less than about 1/100th and not more than 1/12th of the bromine in the bromobutyl is reacted with the amine compound.
    Type: Grant

  • Aldehyde modified polymers
    Patent number: 4168369
    Abstract: Synthetic elastomer compositions of high green strength comprise the reaction product of a rubbery polymer of a conjugated alkadiene having a small number of aldehyde groups attached to and randomly distributed along the polymer chain, and a polyamine having at least two non-tertiary amine groups. An example is a copolymer of styrene, butadiene and cinnamaldehyde (0.5 parts by weight) reacted with p-phenylene diamine, in an amount of 1 mole diamine per mole of cinnamaldehyde.
