## Abstract A longβlived metastable βnew meltβ state of polymers has been recently reported, where monomers exhibit different mobilities due to an unusual distribution of entanglements. We study the relaxation of (fully disentangled) globules to the entangled state by means of computer simulations,

## Abstract The role of entanglements in obtaining a homogeneous product of ultra high molecular weight polyethylene (UHMWβPE) has been explored. Studies performed in this report show that a disentangled state before melting is a prerequisite to obtain homogeneous products of an intractable polymer
## Abstract An attempt was made to measure the effects of molecular entanglements on the rheological properties of polymer melts. Two classes of polymers were studied; glassy atactic polystyrene polymers covering a 60βfold range in molecular weight, and semicrystalline highβdensity polyethylene fro
