This invention relates to a composition for plug in a base-isolated structure capable of providing a plug for base-isolated structure having sufficient damping performance, displacement following property and the like, and more particularly to a composition for plug in a base-isolated structure characterized by including powder and an elastomer composition formed by compounding an elastomer component with a reinforcing filler.

A process that enables the formation of a high damping, soft polymer gel includes reacting a maleimide copolymer with a maleated polyalkylene and an alkyl diamine under substantially dry conditions sufficient to form a polyalkylene-grafted maleimide copolymer product which then is dispersed with an extender sufficient to form the gel. The steps can be carried out sequentially in a high shear mixer without the need for intermediate steps of cooling and grinding the reaction product of one step before proceeding to the next.

A polymeric reticulated structure is prepared by mixing an ethylene-propylene copolymer having an ethylene content of at least 60% by weight or a thermoplastic block copolymer terminated with a crystalline ethylene block with a low molecular weight material. The low molecular weight material is trapped in the three-dimensional continuous network the copolymer forms.
