Methods of making pressure sensitive adhesive compositions
Disclosed is a method comprising: a) dispersing a first monomer mixture comprising least one least monomer, the first monomer mixture having a total glass transition temperature (Tg) in the range of from −10° C. to −65° C. with a surfactant and an initiator in an aqueous medium; b) when the first monomer mixture is completely dispersed, adding a second monomer mixture comprising at least one monomer, the second monomer mixture having a Tg at least 20° C. greater than the Tg of the first monomer mixture, to the aqueous medium; c) when the second monomer mixture is completely dispersed, adding a third monomer mixture comprising at least one monomer, the third monomer mixture having a Tg in the range of from −25° C. to 50° C.; and d) forming a polymer with the first, second, and third monomer mixtures. Also disclosed is a pressure sensitive adhesive comprising the polymer formed by this method.

Rubbery polymer, graft copolymer, and thermoplastic resin composition
A graft copolymer has good moldability and good continuous moldability, and a thermoplastic resin molded article having excellent impact resistance can be produced. A method can produce the graft copolymer. A graft copolymer (B-I) produced by grafting at least one vinyl monomer (b-I) selected from the group consisting of an aromatic vinyl, an alkyl (meth)acrylate, and a vinyl cyanide to a rubbery polymer mixture including a rubbery polymer (A-I) and a hydrophobic substance, the rubbery polymer (A-I) including an alkyl (meth)acrylate unit and a multifunctional monomer unit copolymerizable with the alkyl (meth)acrylate, the hydrophobic substance having a kinematic viscosity of 5 mm.sup.2/s or more at 40° C. or a kinematic viscosity of 2 to 4 mm.sup.2/s at 100° C., a principal constituent of the hydrophobic substance being a hydrocarbon. A thermoplastic resin composition includes the graft copolymer (B-I). A molded article produced uses the thermoplastic resin composition.
