摘要:
Disclosed in one aspect is a voltaic cell assembly comprising one or more voltaic cells, a photovoltaic cell in one embodiment; an elastomeric film and a transparent film, the voltaic cell sandwiched there between. The elastomeric film can be formed from a natural rubber or an isobutylene-based elastomer. More particularly, the elastomeric film may comprise a DVA of a polyamide and a functionalized poly(isobutylene-co-p-methylstyrene). The assembly described is useful for a number of end use articles including roofing shingles, automotive components, building components, and, in general, solar arrays.
摘要:
Processes for producing high pressure polyethylene and processes for increasing the crosslinkability of high pressure polyethylene are disclosed. The processes comprise controlling particular reaction parameters that have been found to promote crosslinkability in the resulting high pressure polyethylene. High pressure polyethylenes having improved crosslinkability are also disclosed.

摘要:
Elastomeric compositions comprising at least one C4 to C7 monoolefin elastomer, at least one polyalphaolefin, and optionally at least one hydrocarbon polymer additive are disclosed. The PAO comprises oligomers of one or more C2 to C20 alpha-olefins having a kinematic viscosity at 100° C. of 3 to 3000 cSt and a Mw/Mn of less than 4. In one aspect, the elastomeric composition may have improved flex fatigue properties and have a fatigue life of 450,000 Kc or more as measured by ASTM D 412 die C. In another aspect, an elastomeric composition may have improved impermeability and have a permeation coefficient at 40° C. of 160 cc*mm/(m2−day) or less.
