Kansai patents starch-based coating
Patent No. U.S. 7,838,592 B2
Kansai Paint Co. has been granted a patent
for a starch-based coating composition
comprised of a naturally derived resin and
a resin composition obtained by reacting
a starch and/or a starch that has been esterified, etherified, oxidized, acid treated or
dextrinated or modified by comprising one
or more groups selected from the group
consisting of aliphatic saturated hydrocarbon groups, aliphatic unsaturated hydrocarbon groups, and aromatic hydrocarbon
groups, which are bonded by ester bonds
and/or ether bonds to the starch or to a decomposition product of a starch that has
been processed by a low molecularization
treatment with an enzyme, acid or oxidizing agent, with a compound containing an
isocyanate group obtained by reacting a
polyisocyanate compound and a polyhydric alcohol.
Dow patents amphiphilic block
copolymer-modified epoxy
resin
Patent No. U.S. 7,820,760 B2
Dow Global Technologies Inc. has obtained a patent for a curable adhesive
epoxy resin composition comprised of an
epoxy resin; an amphiphilic block copolymer containing at least one epoxy resin
miscible block segment and at least one
epoxy resin immiscible block segment;
wherein the immiscible block segment is
comprised of at least one polyether structure provided that the polyether structure
of the immiscible block segment contains
at least one or more alkylene oxide
monomer units having at least four carbon
atoms; in an amount such that when the
epoxy resin composition is cured, the bond
strength of the resulting cured epoxy adhesive resin composition increases compared
to an epoxy resin composition without the
amphiphilic polyether block copolymer;
and at least one curing agent; wherein the
at least one epoxy resin miscible block segment contains a polyethylene oxide block,
a propylene oxide block, or a poly(ethyl-
ene oxide-co-propylene oxide) block; and
the at least one epoxy resin immiscible
block segment contains a polybutylene
oxide block, a polyhexylene oxide block,
or a polydodecylene oxide block.
Cabot patents multi-stage
process for making carbon
black
Patent No. U.S. 7,829,057 B2
Cabot Corp. has been granted a patent
for a process of making a carbon black
product comprised of in a multi-stage carbon black reactor having a converging diameter section, forming a stream of hot
gases at a stage having a diameter and at
a location upstream of where any of carbon black yielding feedstock is introduced into the multi-stage carbon black
reactor, downstream of the converging diameter section, forming a precursor consisting essentially of a first carbon black
in a first carbon black formation site in
the multi-stage carbon black reactor comprised of introducing a first carbon black
yielding feedstock and the hot gases into
the first carbon black formation site, and
downstream of where the first carbon
black yielding feedstock is introduced,
then introducing a second carbon black
yielding feedstock to the precursor in a
second carbon black formation site in the
reactor and forming the carbon black
product in the second carbon black formation site before a complete quench
zone, and further is comprised of introducing at least one substance containing
at least one Group IA or Group IIA element prior to and/or during introducing
the second carbon black yielding feedstock, wherein the second carbon black
formation site is located downstream
from the first carbon black formation site
in a direction of gas flow in the reactor,
and wherein no oxidizing source and no
fuel source for generating hot combustion
gases is introduced after formation of the
precursor, and wherein the first carbon
black formation site and second carbon
black formation site have a temperature
difference (Δ) of 200° C or more as determined from respective first and second
temperatures determined in the reactor
where the first and second carbon black
yielding feedstocks are respectively introduced in the reactor, and wherein the second carbon black yielding feedstock is at
least 15% by weight of the total amount
by weight of carbon black yielding feedstock, wherein the first carbon black
yielding feedstock and second carbon
black yielding feedstock are introduced at
stages of the multi-stage carbon black reactor having diameters that are narrower
than the diameter of the stage of where
the stream of hot gases is formed; and the
carbon black product consisting essentially of a carbon black having a DBP in
a range of from approximately 30 to 150
cc/100 g and an STSA in a range of from
10 to 180 m2/g.
Evonik patents carbon black
method
US2011076608
Carbon black, method for its manufacture
and application (discloses a carbon black
with a content of polycyclic aromatic hydrocarbons measured by the 22 PAH
method of less than 5 ppm and an STSA
surface area of less than 90 m2/g. The carbon black is prepared by treating the
starting carbon black with electromagnetic radiation. The carbon black can be
used in rubber, plastics, printing inks, liquid inks, inkjet inks, toners, coating materials, paints, adhesives, batteries, pastes,
paper, fuel cells, bitumen, concrete and
other building materials).
