POLYMER COMPOSITIONS COMPRISING CYCLIC OLEFIN POLYMERS, POLYOLEFIN MODIFIERS AND NON-FUNCTIONALIZIED PLASTICIZERS

摘要

This invention relates to a polymer composition comppsmg (a) greater than 30 wt % (based upon the weight of the composition) of a cyclic olefin polymer having a Tg greater than 60 degrees C and having a T, heat of fusion (AHf) of 40 J/g or less, (b) from 1 to 50 wt % (based upon the weight of the composition) of an acyclic olefin polymer modifier having a glass transition temperature of less than 0 degrees C, (c) from 0 1 to 50 wt % (based upon the weight of the composition) of a non-functionalized plasticizer having a kinematic viscosity at 100 degrees C of 3 to 3000 cSt, a viscosity index of 120 or more, a pour point of O?C or less and a flash point of 200 degrees C or more
