As a rule, larger alkyl groups on a silane will have lower VOC, and a higher alkoxy group will have lower VOC.
Alkyl group carbon chain length and density strongly affect the mechanical reinforcement of functional ized MWCNTs.
The interaction between butyl group of n-butyl methacrylate and alkyl group of alkyl acrylate increases with an increase in the number of carbon atoms in alkyl acrylate monomer and destabilizes the copolymer because of steric hindrance because it creates higher chain stretching or larger hydrodynamic radius in solution.
but decreased when the alkyl group of the alkyltriethoxysilanes increased in size.
From that table, it can be seen that the long-chain alkyl groups attached to the nitrogen atom of carbazole greatly enhance the solubility of ferrocenium salts, especially in polar solvents and epoxides.
The copolymer, representing 1-20% by weight, is selected from the group consisting of copolymers of propylene with 45-60% by weight of one or more CH2_CHR alkenes, where R is an alkyl group containing 2 to 6 carbon atoms or copolymers of propylene with 45-60% by weight of the one or more CH2_CHR alkenes and with 0-6% by weight ethylene; copolymers of 20 to 80% by weight ethylene with one or more CH2_CHR_ alkenes, where R_ is an alkyl group containing from 1 to 6 carbon atoms, the copolymers of ethylene containing from 0-30% of fraction insoluble in xylene at 25[degrees]C, or copolymers of 20-80% by weight ethylene with one or more of the CH2_CHR_ alkenes and from 1-10% by weight of a diene.
1, for the preparation of organoclay were selected in order to investigate the effects of bulky alkyl groups, hydrogen bonding between hydroxyl groups of BHL and VER, and the reaction of VER with the unsaturated C = C groups of DEM and BHLV.
has received a patent for a pigment dispersing resin which is a copolymer of sulfonic group-containing polymerizable unsaturated monomer; polyoxyalkylene chain-containing nonionic polymerizable unsaturated monomer; (meth)acrylic acid ester type polymerizable monomer having two tertiary alkyl groups per molecule and/or (meth)acrylic acid ester type polymerizable monomer having one tertiary alkyl group and one secondary hydroxyl group per molecule; and other ethylenically unsaturated monomer and where the copolymer is obtained by the copolymerization of monomers at the following proportion on the basis of the total weight of monomers.
This is attributed to the decrease in the bulkiness of the pendent alkyl group, which also increases the glass transition temperature ([T.
4], wherein R is same or different, and represents an alkyl group having one to five carbon atoms.
6] alkyl group, said copolymer containing about 85 to 99.
The degree of alkylation decreased with the increasing carbon number of the alkyl group and showed smaller values in the case of branched compounds.
