The present invention relates to a rubber composition for a tread, including: a rubber component; an aromatic vinyl polymer
; silica; and a mercapto group-containing silane coupling agent, wherein the aromatic vinyl polymer
is a resin obtained by polymerization of a-methylstyrene and/or styrene and the amount of the aromatic vinyl polymer
is 3 to 25 parts by mass and the amount of the silica is 15 to 150 parts by mass, based on 100 parts by mass of the rubber component.
The Swiss scientists at ETH Zurich, have created the circuit with parylene, which was deposited onto vinyl polymer
, before printing on to the parylene, Mashable reported.
However, equal parts used with Carboxy vinyl polymer
(2% each) caused a decline in viscosity.
has obtained a patent for an aqueous coating composition comprised of a blend of 20% to 60% weight of a multistage vinyl polymer
(A) and 80% to 40% weight of a vinyl oligomer-polymer (B) based on the total weight of (A) and (B); wherein the multistage vinyl polymer
(A) is comprised of 5% to 40% weight of at least one hard polymer stage (i) having a Tg>50 [degrees] C; and 95% to 60% weight of at least one soft polymer stage (ii) having a Tg<5 [degrees] C; based on the total weight of (i) and (ii); and wherein the vinyl oligomer-polymer (B) is comprised of 15% to 50% weight of at least one alkaline soluble oligomer (iii); and 85% to 50% weight of at least one vinyl polymer
(iv) having a Tg in the range of from -20[degrees] to 30[degrees] C; based on the total weight of (iii) and (iv).
They produced a branched vinyl polymer
carrying dendrons, where the vinyl polymer
is made from a monofunctional vinyl monomer.
PIB is a vinyl polymer
similar to polyethylene and polypropylene in structure.
The vinyl polymer
is unusual because it is based only in part on hydrocarbon feedstocks and the other part is based on chlorine.
Emission of volatile gasses during production of vinyl polymers
continues to challenge manufacturers.
These fibers can be used in vinyl polymers
as well as condensation polymers with good results.
Various types of polymers such as vinyl polymers
and conducting polymers can be adopted in this system.
It is important to choose synthetic polymer those containing functional groups that can potentially interact with the hydroxyl groups of cellulosic chain such as polyamides polyesters and vinyl polymers
. In this paper grafting of synthetic vinyl polymers
onto cellulose extracted from kenaf fiber offers the potential of preparing a new class of engineering materials.
