The present invention is an antimicrobial agent containing a polyalkyleneimine derivative formed by adding a substituent group having a structure of a following Formula (1) to a nitrogen atom of polyalkyleneimine.&#x2014;CHCH(OH)CH&#x2014;O&#x2014;R&#x2003;&#x2003;(1) In the formula, Rrepresents an alkyl group with 6 to 20 carbon atoms, an alkenyl group with 6 to 20 carbon atoms, an aryl group with 6 to 20 carbon atoms, or &#x2014;(CHCHO)&#x2014;R. Rrepresents an alkyl group with 6 to 20 carbon atoms, an alkenyl group with 6 to 20 carbon atoms, or an aryl group with 6 to 20 carbon atoms. n represents an integer of 1 to 50.

Antimicrobial agent containing polyalkyleneimine derivative

An &#x3b1;-(unsaturated alkoxyalkyl)acrylate composition is provided which enables an &#x3b1;-(unsaturated alkoxyalkyl)acrylate product to be stored at a high purity for an extended period of time and can fully suppress problems such as discoloration and gelation from arising during polymerization, and a method of safely preparing &#x3b1;-(unsaturated alkoxyalkyl)acrylate compositions industrially, with high purity. The composition includes an &#x3b1;-(unsaturated alkoxyalkyl)acrylate of a specific structure and an antioxidant, the content of the antioxidant being from 0.03 to 0.5 wt % per 100 wt % of the &#x3b1;-(unsaturated alkoxyalkyl)acrylate.

&#x3b1;-(unsaturated alkoxyalkyl) acrylate composition and process for production thereof

Disclosed is an optical planar thermoplastic resin composition including a lactone ring-containing polymer as a main component thereof, or including a lactone ring-containing polymer and at least one other thermoplastic resin. The optical planar thermoplastic resin composition of the present invention has high transparency, high heat resistance, and high optical isotropy, and therefore, can sufficiently exhibit characteristics according to various optical applications.

Optical planar thermoplastic resin composition

In the method of the present invention for producing fatty acid alkyl ester and/or glycerin, as a heat source for an alcohol refining step of refining alcohol from unreacted alcohol that remains without reacting in a first reaction step, at least a part of heat of the unreacted alcohol is used. This allows reducing costs in production of fatty acid alkyl ester and/or glycerin over a solid catalyst.
