An intracellular delivery vehicle of which surface is covered by a positive charge, an intracellular delivery complex in which a component or compound desired is loaded in the intracellular delivery vehicle, a temperature-sensitive probe comprising the intracellular delivery complex, and a method for measuring the intracellular temperature by the temperature-sensitive probe are disclosed. The intracellular delivery vehicle is useful on account of its capability of easily delivering the component or compound desired inside the cell without inhibiting cell proliferation.

SET-LRP polymerization of acrylic monomers under acidic conditions is described. The source of the acidity may be the solvent (e.g., an acetic acid-containing solvent) or in the monomer content (e.g., acrylic acid or methacrylic acid, optionally in combination with other monomers such as methyl methacrylate).

The invention provides an SRT material (lubricant) applicable to machine elements such as bearings, seals or guides (guiding mechanisms) that constitute a slide part of a machine. A lubricant and an SRT material are disclosed.

Provided are a method for producing a multibranched polymer that can produce a multibranched polymer having a narrow molecular weight distribution in a one-pot procedure and the multibranched polymer. A method for producing a multibranched polymer includes the step of polymerizing a first vinyl monomer having a polymerization-initiating group in an -position of a vinyl bond and a second vinyl monomer free of polymerization-initiating group in an -position of a vinyl bond by a living radical polymerization.

A non-humidified proton-conductive membrane according to the present invention includes a polymer and a proton-conductive substance. The polymer includes a glassy or crystalline first site having a glass-transition temperature or melting temperature higher than the service temperature of the proton-conductive membrane and a second site capable of forming a noncovalent bond. The proton-conductive substance includes a proton-releasing/binding site capable of noncovalently binding to the second site of the polymer and a proton coordination site capable of coordinating to protons, the proton-releasing/binding site and the proton coordination site being included in different molecules that interact with each other or being included in the same molecule. A proton-conductive mixed phase that includes the second site to which the proton-releasing/binding site of the proton-conductive substance is bound and the proton-conductive substance is lower than the service temperature of the proton-conductive membrane. The amount of the proton-releasing/binding site is excessively large compared with the amount of the second site of the polymer.

A random copolymer, a preparation method of the random copolymer, a drilling fluid containing the random copolymer. The random copolymer contains structural unit (A) represented by formula (1), structural unit (B) represented by formula (2), structural unit (C) represented by formula (3), and structural unit (D) represented by formula (4) or (5):

##STR00001##

wherein X is halogen. When the random copolymer is used as a filter loss reducer in a high-calcium drilling fluid, the filter loss of the high-calcium drilling fluid can be reduced.
