摘要：
Crosslinked elastomeric and/or thermoplastic closed-cell foams having low densities are prepared from an admixture which comprises a crosslinkable thermoplastic and/or elastomeric polymer, a free radical initiator which is activated at temperatures from about 50°F to about 350°F, and a t-alkylhydrazinium salt or a carbonylhydrazine.
