Modification of the silica colloids (siloxane and fluorinated
alkyl groups) were used to drive the colloids to the air-film interface.
PMIA with unsaturated
alkyl groups was reacted with thiols to examine the reactivity of the derivatives.
This suggested that the inclusion complex made of [gamma]CD and MT included a form covering the
alkyl group of MT from the cavity of a wide edge of CD with respect to the
alkyl group of the -CH (h) in MT.
ASCP and the PM (ASCP/UR at a molar ratio of 1/12) had peaks due to the
alkyl group (-C[H.sub.2]-) of ASCP at 5664 [cm.sup.-1] and 5772 [cm.sup.-1] and a peak due to the carbonyl group (-C=O-) of ASCP at 5444 [cm.sup.-1] while UR had peaks due to in-phase vibration of N-H of UR at 6820 [cm.sup.-1] and out-phase vibration of N-H of UR at 6532 [cm.sup.-1].
The transfer of an
alkyl group from a quaternary ammonium salt has been briefly mentioned in the case of 2-chlorophenothiazine [6].
Applications of viologens [1] cannot be limited to its short
alkyl group substituents.
BASF has obtained a patent for a n aqueous coating formulation comprised of a substituted, branched polyethyleneimine, which is obtained by a process comprised of reacting a branched polyethyleneimine having a weight-average molecular weight of from 500 to 10,000 g/mol with a carboxylic acid derivative of formula (I) R--(C=0)X (I), wherein R is a C5 to C18
alkyl group or a C5 to C18 alkenyl group, X is a halogen, a hydroxyl group, or a group R--(C=0)--O--, a molar amount of the carboxylic acid derivative in the reacting is from 3 to 10 mol percent of a molar amount of ethyleneimine employed in preparing the branched polyethyleneimine, the reacting is comprised of formation and removal of a byproduct HX, and the formulation is configured to coat a substrate that is comprised of tannin.
As shown in Figure 1, PA, PPE, and PME were modified by changing the coil length of the substituted
alkyl group (PaD-alkyls), and HPA, HPPE, and HPME were modified with the substitution of the hydroxyl group (PaD-OHs).
This means that one or more of the alkoxy groups has been replaced with a metallic species, and that the
alkyl group is a methyl group.
The solid plasticizer comprises at least two different benzotriazole derivatives selected from compounds represented by following formula: R1 is one of a hydrogen atom, a halogen atom and an
alkyl group; m is an integer of one to four; and X is one of a hydrogen atom, an
alkyl group, an aryl group, an aralkyl group and a group represented by following formula: R2 is one of a hydrogen atom, a halogen atom, an
alkyl group and hydroxyl group and n is an integer of one to five.
The modified oligodeoxynucleotide according to the invention has the sequence 5'-TxAxTxTxCxCxGxTxCxAxT-3'-O--PO.sub.2 --O--R (SEQ ID NO:1), wherein X is an internucleotide linkage of type o or s, with the proviso that x is an s linkage at least 4 times and at most 9 times, and o means a phosphodiester internucleoside linkage, s means a phosphorothioate internucleoside linkage, R means a C.sub.8 -C.sub.21
alkyl group, --(CH.sub.2 --CH.sub.2 O)n-(CH.sub.2).sub.m --CH.sub.3, or --CH.sub.2 --CH(OH)CH.sub.2 O--(CH.sub.2).sub.q --CH.sub.3 wherein n is an integer from 1 to 6, m is an integer from 0 to 20 and q is an integer from 7 to 20 and A is 2'-deoxyadenosine, G is 2'-deoxyguanosine, C is 2'-deoxycytidine and T is thymidine.
