Copolymers of one or more halogenated olefins and one or more halogenated co-monomers selected from the group consisting of halogenated alkenyl ethers, halogenated alkenyl esters, and halogenated (meth)acrylates are useful in various end-use applications wherein the presence of halogen (e.g., fluorine) in the copolymer imparts one or more desirable properties, as compared to analogous copolymers not containing halogen.

The present invention has an object to provide a composition or the like capable of forming a film having high resolution and high sensitivity. The above object can be achieved by the following compound. An iodine-containing (meth)acrylate compound represented by the general formula (1):

wherein R.sup.1 represents a hydrogen atom, a methyl group, or halogen; each R.sup.2 independently represents a hydrogen atom, a linear organic group having 1 to 20 carbon atoms, a branched organic group having 3 to 20 carbon atoms, or a cyclic organic group having 3 to 20 carbon atoms; A represents an organic group having 1 to 30 carbon atoms; n.sup.1 represents 0 or 1; and n.sup.2 represents an integer of 1 to 20.

The compound is represented by general formula (i). In the compound, in a group K.sup.i1, at least two secondary carbon atoms in an alkyl group (a linear alkyl, halogenated alkyl, or cyanogenated alkyl group having 3 to 40 carbon atoms) are replaced with —C(═X.sup.i1)— and/or —CH(—CN)—, where X.sup.i1 is an oxygen atom, a sulfur atom, NH, or NR.sup.13; in addition, a group A.sup.i2, a group A.sup.i3, or the group K.sup.i1 includes, as a substituent, at least one P.sup.i1-Sp.sup.i1- group, where P.sup.i1 is a polymerizable group, and SP.sup.i1 is a spacer group or a single bond. The liquid crystal composition including the compound represented by general formula (i) can be adsorbed onto substrates between which a liquid crystal layer is held, and, consequently, without the use of an alignment film, liquid crystal molecules can be maintained in a state in which the liquid crystal molecules are aligned in a vertical direction. ##STR00001##

The present invention addresses the problem of suppressing corrosion of a molding machine or mold when molding a polybutylene terephthalate resin composition that uses a halogenated benzyl acrylate-based flame retardant as a flame retardant and suppressing corrosion of a metal terminal in an insert-molded article that uses the polybutylene terephthalate resin composition. The problem is solved by a polybutylene terephthalate resin composition that uses a halogenated benzyl acrylate-based flame retardant as a flame retardant, wherein the amount of halogenated aromatic compounds such as chlorobenzene in the manufacturing process for the flame retardant is suppressed.
