摘要: The present invention is directed to PE-100 ethylene copolymers and pipe made thereof having a Tabor abrasion between about 0.01 and about 0.001 grams lost/1000 revolutions. These copolymers are formed by contacting ethylene with at least one mono-1-olefin comonomer having from 2 to about 10 carbon atoms per molecule in a reaction zone under polymerization conditions in the presence of a hydrocarbon diluent, a catalyst system, and a cocatalyst. Additionally, the comonomers may be selected from mono-1-olefins having 4 to 10 carbon atoms, such as, 1-hexene, 1-butene, 4-methyl-1-pentene, 1-octene, and 1-decene. Further, these ethylene copolymers may be employed to produce PE-100 pipe having both small diameters and diameters in excess of 42 inches substantially without sagging or other gravitational deformation. Copolymers of ethylene and 1-hexene are disclosed which are used to produce PE-100 pipe.

摘要: The present application relates reinforced poly(arylene sulfide) compositions and processes of producing the reinforced poly(arylene sulfide) compositions. The reinforced poly(arylene sulfide compositions can be prepared by blending the reinforcing agent with the poly(arylene sulfide) or by including the reinforcing agent in the process to produce the poly(arylene sulfide). Reinforcing agents which can be utilized are graphenes (e.g., single-walled carbon nanotubes). The inclusion of the graphene reinforcing agent in the poly(arylene sulfide) composition affects the crystallization properties and/or the conductivity of the melt processed poly(arylene sulfide) compositions.
