    摘要： The present invention relates to a foam, a process for preparing the foam and an article containing the foam. The foam contains a coupled propylene polymer and has a density in of from 9.6 to 801 kg/m3 and has either a foamability factor of more than 1.8 to less than 2.8 and an open cell content less than 20 percent, or a foamability factor of at least 2.8 and less than 15 and an open cell content of less than 50 percent. The process includes heating a coupled propylene polymer having a melt flow rate from 0.2 to 20 g/10 min and a melt strength of at least 39 cN to a molten state to produce a molten polymer material and mixing said molten polymer material with a blowing agent under conditions to produce a foamed material having a density in the range of from 9.6 to 801 kg/m3.

    摘要： Seeded cation-exchange resin beads are particularly susceptible to oxidative degradation which results in the leaching of organic carbon fragments. The leachability of organic carbon fragments of molecular weights greater than 1000 g/mol is reduced to less than 800 ppm by effectively crosslinking the copolymers that comprise the seeded cation-exchange resin beads. Crosslinking can be achieved either during sulfonation by increasing sulfone bridge formation or before sulfonation by either alkylene bridge formation or by incorporation and subsequent activation of a crosslinkable functionality in the copolymer that forms the seed in the seeded polymer bead process.

    摘要： Cellulose ethers are described herein which are useful in food compositions. In these cellulose ethers the ether substituents are methyl groups, hydroxyalkyl groups, and optionally alkyl groups being different from methyl, the cellulose ether has a DS(methyl) of from 1.65 to 2.20, an MS(hydroxyalkyl) of from 0.10 to 1.00, and hydroxy groups of anhydroglucose units are substituted with methyl groups such that [s23/s26−0.2*MS(hydroxyalkyl)] is 0.35 or less, wherein s23 is the molar fraction of anhydroglucose units wherein only the two hydroxy groups in the 2- and 3-positions of the anhydroglucose unit are substituted with methyl groups and wherein s26 is the molar fraction of anhydroglucose units wherein only the two hydroxy groups in the 2- and 6-positions of the anhydroglucose unit are substituted with methyl groups.
