摘要:
Disclosed are a thermochromic resin composite and a dimmer allowing easy adjustment of a clouding point. The thermochromic resin composite is predominantly composed of an aqueous medium, an amphiphilic linear polymer changeable between a transparent state and an opaque state in the aqueous medium depending on temperature, and an amphiphilic endless polymer changeable between a transparent state and an opaque state in the aqueous medium depending on temperature, and the amphiphilic linear polymer and the amphiphilic endless polymer in the aqueous medium have one clouding point, the clouding point changing in accordance with a mixing ratio of the amphiphilic linear polymer to the amphiphilic endless polymer.

摘要:
Novel cellulose derivative, process for preparing the same and sulfur dioxide gas permselective membrane comprising said derivative.Hydrocarbysulfinylethyl cellulose represented by the formula (I): ##STR1## wherein, X may be the same or different and represents hydrogen atom or hydrocarbylsulfinylethyl group represented by the formula (II): ##STR2## wherein, R may be the same or different and represents an alkyl group having 1 to 6 carbon atoms or a phenyl group,with the average substitution degree with the hydrocarbylsulfinylethyl group of the formula (II) per glucose unit being at least 0.05, and sulfur dioxide gas permeation membrane comprising said cellulose derivative. This membrane is excellent in sulfur dioxide gas permselectivity.
