    Abstract: The present invention relates to the use of a polymer containing acid groups as a dispersant for stabilising an aqueous inorganic pigment slurry, wherein the polymer containing acid groups comprises polyether groups of the structural unit (I) *—U—X-(AlkO)n—W (I) where * indicates the bonding site to the polymer containing acid groups. U represents a chemical bond or an alkylene group having 1 to 8 carbon atoms. X is oxygen or an NR1 group, n is an integer with a mean, based on the polymer containing acid groups, in the range from 3 to 300, Alk is C2-C4-alkylene, where Alk may be the same or different within the (Alk-O)n group, W is a hydrogen, C1-C6-alkyl or aryl radical or is the Y—F group where Y is a linear or branched alkylene group which has 2 to 8 carbon atoms and may bear a phenyl ring, F is a nitrogen-bonded 5- to 10-membered nitrogen heterocycle which may have, as ring members, as well as the nitrogen atom and as well as carbon atoms, 1, 2 or 3 additional heteroatoms selected from oxygen, nitrogen and sulphur, where the nitrogen ring members may have an R2 group, and where 1 or 2 carbon ring members may be in the form of carbonyl groups, R1 is hydrogen, C1-C4-alkyl or benzyl, and R2 is hydrogen, C1-C4-alkyl or benzyl, wherein the inorganic pigment slurry is selected from the group consisting of titanium dioxide slurry, calcium hydroxide slurry, ultrafine precipitated calcium carbonate (PCC) slurry and ground calcium carbonate (GCC) slurry. The invention provides pigment slurries having improved viscosity characteristics together with improved stability over time.

    Abstract: The present invention relates to the use of at least one N,N-dimethylamide as an additive in an elastomeric composition for producing a tread band for vehicle wheels, wherein the N,N-dimethylamide has the formula: formula (I), wherein: R is a C6-C12 alkyl group, and R′ and R″ are methyl. A further aspect of the present invention concerns a vulcanised elastomeric material for producing a tread band for vehicle wheels obtained by vulcanising an elastomeric composition comprising (a) at least one elastomeric polymer, (b) at least one reinforcing filler selected among hydroxides, oxides and hydrated oxides, salts and hydrated salts of metals or mixtures thereof and (c) at least one N,N-dimethylamide of formula (I). An additional aspect of the present invention concerns a tread band for vehicle wheels comprising a vulcanised elastomeric material, which vulcanised elastomeric material is obtained by vulcanising an elastomeric composition comprising (a) at least one elastomeric polymer, (b) at least one reinforcing filler selected among hydroxides, oxides and hydrated oxides, salts and hydrated salts of metals or mixtures thereof and (c) at least one N,N-dimethylamide of formula (I). The inventive use and the inventive composition provide effective elastomeric materials particularly suitable for use as treads on vehicle tyres.

    Abstract: A method of increasing the throughput and/or decreasing the energy usage of a pulping process includes the steps of providing a plurality of lignocellulosic chips, providing a refining composition, applying the refining composition to the plurality of lignocellulosic chips, and mechanically refining the plurality of lignocellulosic chips to form pulp. The refining composition includes water and a lubricating additive including the reaction product of a sugar and an alcohol. The step of applying the refining composition to the lignocellulosic chips is conducted less than 5 minutes prior to, or concurrently with, the step of mechanically refining the wood chips to form pulp.
