摘要:
Interpenetrated polyolefin network for use in recovering or containing hydrocarbons such as hydrocarbons contained in oil, are disclosed. Advantageously, the interpenetrated polyolefin networks absorb the hydrocarbon, including viscous hydrocarbons and crude oils, to form a gel that can be collected and processed by heat to release the collected hydrocarbons.
摘要:
The present application relates to an encapsulant for a PV module, a method of manufacturing the same and a PV module. The encapsulant according to an embodiment of the present application has excellent heat resistance or the like and improved creep physical properties, and thus even when the encapsulant is used under conditions of a high temperature and/or high humidity for a long time, deformation is small and the encapsulant can exhibit excellent adhesive strength. Accordingly, when the encapsulant is applied to a PV module, durability or the like may be improved.

摘要:
A process for epoxidation of an unsaturated polymer involves mixing an unsaturated polymer and a peroxy acid in an absence of solvent to produce an epoxidized polymer. The process may require no catalyst, require no or little applied external heat input, require no applied cooling, require less epoxidation agent, be faster and/or result in more efficient conversion of the unsaturated polymer.

摘要:
A foamable formulation composition comprises at least 50 weight percent of an ethylene/α-olefin interpolymer having a Comonomer Distribution Constant in the range of from 15 to 250; a density in the range of from 0.875 to 0.963 g/cm3; a melt index (I2) in a range of from 0.5 to 5 g/10 minutes; and long chain branching frequency in the range of from 0.05 to 3 long chain branches (LCB) per 1000 C; (2) a blowing agent; and (3) a cross link agent. The formulation may be processed to result in a foam having a density ranging from 0.05 to 0.25 g/cm3 and have properties such as split tear, compression set, and/or shrinkage percentage that are improved in comparison with otherwise-identical formulations lacking the identified ethylene/α-olefin interpolymer in comparable amount. These foams may be particularly useful for a variety of applications, including, in particular, footwear applications.
摘要:
A dynamically vulcanized alloy containing an elastomer and a thermoplastic resin is prepared by a process wherein supercritical fluid is injected into the thermoplastic elastomeric material as the material is mixed in an extruder. The material is mixed under conditions such that the thermoplastic elastomeric material is dynamically vulcanized wherein the elastomer forms a discontinuous dispersed of small particles in a continuous phase of the thermoplastic resin. The DVA material may then be directly formed into film or sheets by the use of at least one set of rolls located adjacent to the extruder outlet.

Disclosed is a poly(4-methyl-1-pentene) resin composition having an excellent balance between micropore formability and toughness, which can sufficiently form fine pores by drawing and does not cause a break during drawing. The poly(4-methyl-1-pentene) resin composition contains 0-90 parts by mass of a 4-methyl-1-pentene homopolymer (A) and 10-100 parts by mass of a 4-methyl-1-pentene copolymer (B) having a structural unit derived from 4-methyl-1-pentene and a structural unit derived from a C 2-20 ±-olefin other than 4-methyl-1-pentene. The content of the structural unit derived from a C 2-20 ±-olefin other than 4-methyl-1-pentene is 0.1-2.1% by mass relative to the total amount of the homopolymer (A) and the copolymer (B). The poly(4-methyl-1-pentene) resin composition also contains 0.1-800 ppm of a nucleator (C) relative to the total weight of the homopolymer (A) and the copolymer (B).
