    摘要: Polymeric compositions for semiconductor applications comprising 10 to 99 wt. % of norbornene-type cycloolefin monomers represented by one or more of Formula I(a), I(b), and optionally I(c) and/or I(d), 0.0005 to 0.5 wt. % of an addition polymerization procatalyst, and optionally: up to 0.5 wt. % of a cocatalyst, up to 59 wt. % of a crosslinking monomer, up to 50 wt. % of a viscosifier, up to 20 wt. % of a thixotropic additive(s), up to 80 wt. % of a filler, up to 10 wt. % of an antioxidant, and up to 0.6 wt. % of an antioxidant synergist, the total of the components of the formulation adding up to 100%. Such formulations are mass polymerized, or cured, to form polymeric compositions that have properties desirable for a variety of specific electronic, microelectronic, optoelectronic and micro-optoelectronic applications such as die attach adhesives, underfill materials, prepreg binders, encapsulants, protective layers, and other related applications.
