摘要： PURPOSE:To obtain covering material of pack for face and whole body exhibiting the effect in a short time and having effects such as large percutaneous absorption action of skin activation component and excellent workability by composing of polymer film having specific temperature range of melting point or softening point and storage modulus. CONSTITUTION:The aimed covering material of pack is composed of a polymer film having melting point or softening point within the temperature range of 35-70 deg.C and ratio of storage modulus at a temperature 30 deg.C lower than the melting point or softening point to storage modulus at a temperature 30 deg.C higher than the melting point or softening point. Said covering material of pack is able to be used by only softened by heating and stuck on a part of body, then cooled and solidified, thus timewise imposition of user is small. The polymer useful for producing said film is trans-1,4-polyisoprene, etc.

摘要： PROBLEM TO BE SOLVED: To reduce the formyl groups of a formyl-containing polymer into hydroxymethyl groups in high conversion without any crosslinking reaction by catalytically hydrogenating the polymer in the presence of an alcohol and a hydrogenation catalyst. SOLUTION: The formyl-containing polymer can be produced by, for example, a known process comprising hydroformylating a polymer having aliphatic carbon - carbon double bonds in the molecule and obtained by polymerizing a conjugated diene such as 1,3-butadiene, isoprene, or 1,3-pentadiene. The alcohol is exemplified by a primary or secondary monohydric alcohol such as methanol, ethanol, or 2-propanol or a dihydric alcohol such as ethylene glycol or 1,4-butanediol. Among them, a primary or secondary monohydric alcohol is desirable. The hydrogenation catalyst is exemplified by Raney nickel, Raney cobalt, ruthenium carbon, or palladium carbon.
