Abstract:
1. An overmolding composition comprising: 1) an [A]-[B]-[A] copolymer, wherein [A] is a hard-block monomer with a Tg greater than about 30° C. and [B] is a soft-block monomer with a Tg less than about 20° C., and the copolymer comprises greater than 35 wt % of the [A] monomer; 2) a tackifying resin; and wherein the composition has a viscosity less than 75,000 cP at 210° C. measured in accordance with ASTM D3236; wherein the storage modulus (G′) of the composition is greater than 1×10^7 dyne/cm wherein the wt % is based on the total weight of the composition; and wherein the [A] monomer is selected from the group consisting of ethyl methacrylate,isobornyl acrylate, isobornyl methacrylate, cyclohexyl methacrylate, methyl (meth)acrylate and mixtures thereof.
