摘要:
Cationic and cationogenic comb copolymers are disclosed along with personal care products that employ them as a modifier that results in increased sensory attributes and increased effectiveness in the deposition of actives and can also act as a thickening agent. The copolymer includes one or more repeating units derived from olefinically unsaturated cationic or cationogenic comonomers and one or more repeating units having the formula in which Y is a moiety forming part of a copolymer backbone, Z is a moiety that exhibits association with other Z moieties or with other moieties within the ultimate formulation in which the copolymer will be employed, and b is a bond or moiety that links the Z moiety to the Y moiety. In certain embodiments, the copolymer also includes repeating units derived from acrylamide monomers, olefinically unsaturated hydrophilic monomers or other olefinically unsaturated monomers.

A lubricant composition having improved non-Newtonian viscometrics includes at least 85 weight percent of a base oil and 1 to 15 weight percent of a lubricant additive. The additive itself includes 10 to 80 weight percent of a diluent oil and 30 to 80 weight percent of a random co-polymeric viscosity index improver. The viscosity index improver is the free-radical polymerization product of at least 5 to 15 weight percent methyl methacrylate and 5 to 95 weight percent of a C8-C10 alkyl (meth)acrylate. The additive is formed using a method that includes the step of providing the diluent oil, the methyl methacrylate, the C8-C10 alkyl (meth)acrylate, and a free-radical initiator. The method also includes the steps of flowing the diluent oil into a reactor, flowing the methyl methacrylate and the C8-C10 alkyl (meth)acrylate into the reactor independently from the free-radical initiator, and flowing the free-radical initiator into the reactor.

Disclosed is a double-sided adhesive tape that has a difference in adhesion between the front and rear sides thereof and can be produced to have a reduced thickness by a simple method. The double-sided adhesive tape is a sheet-shaped cured product of an adhesive composition containing a resin composition and an inorganic filler. The resin composition contains (A) an acrylate-based monomer, (B) a monomer copolymerizable with (A), (C) a photopolymerization initiator, and (D) a photo-crosslinking agent. The inorganic filler has an average particle diameter of 30 μm or less and is localized on one side of the tape. The surface roughness (center line average roughness Ra) of the tape surface on the side on which the inorganic filler is localized is 0.01 to 0.50 μm.
