ABSTRACT:
Disclosed are compositions and processes for preparing polymeric materials having polymerizable units derived from at least one C8to C30alkyl (meth)acrylate monomer, and at least one chain branching unit. The presence of the chain branching unit suprisingly results in the polymeric composition having non-gelled polymer chains. The polymeric compositions are useful as additives for improving the melt strength of thermoplastic resins.
