Abstract
A melt-blend resin composition prepared by melt-blending includes from 60 parts to 99 parts per hundred weight resin in the blend of an amorphous cycloolefin polymer composition exhibiting a glass transition temperature in the range of from 30° C. to 200° C.; and from 40 parts to 1 part per hundred weight resin in the blend of a partially crystalline, cycloolefin elastomer of norbornene and ethylene preferably having a glass transition temperature in the range of from −10° C. to 15° C. and a crystalline melting temperature in the range of from 60° C. to 125° C. and a % crystallinity by weight in the range of from 5% to 40%. The partially crystalline, cycloolefin elastomer optionally has a second glass transition temperature at less than −90° C.
