Abstract
The present invention has an object to provide a transparent resin material having a low water absorption ratio without deteriorating various properties such as transparency which transparent resin has and also having a controllable refractive index. The present invention provides a transparent resin material containing a polymer capable of forming a formed product having transparency, wherein the transparent resin material comprises a fluorine atom-containing polymer and/or compound and contains 0.3 to 35% by weight of a fluorine atom in 100% by weight of the formed product.
Claims7
A transparent material containing a mixture of 1) a resin capable of forming a formed product having transparency, and 2) a fluorine atom-containing compound, which is represented by the following formula (1):
- in the formula, Z1 represents a divalent organic group or a direct bond between benzene rings;
- n and m each represents an integer of 0 to 5;
- n+m is 1 or more;
- a hydrogen atom in the benzene ring may be replaced with a substituent group other than a fluorine atom,
- wherein the transparent material contains 0.3 to 35% by weight of a fluorine atom in 100% by weight of the formed product,
- and wherein the transparent material contains a ratio of 1 to 100 parts by weight of the fluorine atom-containing compound to 100 parts by weight of the resin capable of forming a formed product having transparency.
A method for using a composition comprising a polymer and/or compound having a fluorine atom directly bonded to an aromatic ring as an additive for resin, wherein the fluorine atom-containing polymer comprises a repeating unit represented by the following formula (12):
- in the formula, R2 represents a divalent organic group having 1 to 150 carbon atoms;
- Z1 represents a divalent organic group or a direct bond between benzene rings;
- m′ and n′ are same or different and each represents the number of fluorine atom bonded to the benzene ring and is an integer of 0 to 4;
- m′+n′ is 1 or more;
- p represents a polymerization degree;
- and a hydrogen atom of the benzene ring may be replaced with a substituent group other than a fluorine atom
- and/or a repeating unit represented by the formula (13):
- in the formula, R1 represents an alkyl group having 1 to 12 carbon atoms, an alkoxy group having 1 to 12 carbon atoms, an alkylamino group having 1 to 12 carbon atoms, an alkylthio group having 1 to 12 carbon atoms, an aryl group having 6 to 20 carbon atoms, an aryloxy group having 6 to 20 carbon atoms, an arylamino group having 6 to 20 carbon atoms, or an arylthio group having 6 to 20 carbon atoms, which each may contain a substituent group;
- R2 represents a divalent organic group having 1 to 150 carbon atoms;
- and p represents a polymerization degree, which method comprises adding said composition to said resin.
