Abstract

Provided is a triazine ring-containing hyperbranched polymer comprising the repeating unit structure represented by formula (1) and having one or more triazine ring terminals, said one or more triazine ring terminals being capped with a compound that differs from the diamine compound serving as the starting material for the polymer and has at least two active hydrogen groups. In addition to the polymer itself exhibiting high heat resistance, high transparency, a high refractive index, high light resistance, high solubility, and low volume shrinkage, it is also possible to use the polymer to provide a composition for film formation capable of yielding a thick film having high hardness.

(In formula (1), R and R′ each independently represent a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, or an aralkyl group, and Ar represents a divalent organic group containing an aromatic ring and/or a heterocyclic ring.)

First claim

The invention claimed is:

1. A triazine ring-containing hyperbranched polymer, comprising recurring units and is capped by capping compounds consisting of one or more amino alcohols,
wherein the recurring units are bonded only to other of the recurring units and/or capping compounds, and
wherein the recurring units in said polymer consist of at least one recurring unit structure of formula (1)

wherein R and R′ are each independently a hydrogen atom, an alkyl group, an alkoxy group, an aryl group or an aralkyl group; and Ar is a divalent organic group which comprises an aromatic ring or a heterocycle or both an aromatic ring and a heterocycle.

2. The triazine ring-containing hyperbranched polymer according to claim 1 , wherein the one or more amino alcohols comprise at least one alkanolamine.

3. The triazine ring-containing hyperbranched polymer according to claim 1 or 2 , wherein Ar is at least one moiety selected from the group consisting of moieties of formulas (2) to (18)

wherein R 1 to R 128 are each independently a hydrogen atom, a halogen atom, a carboxyl group, a sulfo group, an alkyl group of 1 to 10 carbons which may have a branched structure, or an alkoxy group of 1 to 10 carbons which may have a branched structure; W 1 and W 2 are each independently a single bond, CR 129 R 130 , R 129 and R 130 being each independently a hydrogen atom or an alkyl group of 1 to 10 carbons which may have a branched structure, with the proviso that R 129 and R 130 may together form a ring, C═O, O, S, SO, SO 2 or NR 131 , R 131 being a hydrogen atom or an alkyl group of 1 to 10 carbons which may have a branched structure; and X 1 and X 2 are each independently a single bond, an alkylene group of 1 to 10 carbons which may have a branched structure, or a group of formula (19)

R 132 to R 135 being each independently a hydrogen atom, a halogen atom, a carboxyl group, a sulfo group, an alkyl group of 1 to 10 carbons which may have a branched structure, or an alkoxy group of 1 to 10 carbons which may have a branched structure; and Y 1 and Y 2 are each independently a single bond or an alkylene group of 1 to 10 carbons which may have a branched structure.

4. The triazine ring-containing hyperbranched polymer according to claim 3 , wherein Ar has formula (12).

5. The triazine ring-containing hyperbranched polymer according to claim 1 , wherein the recurring unit structure has formula (21)

wherein R and R′ are as defined in claim 1 .

6. The triazine ring-containing hyperbranched polymer according to claim 5 , wherein the recurring unit structure has formula (22)

7. The triazine ring-containing hyperbranched polymer according to claim 2 , wherein the at least one alkanolamine is one or more selected from the group consisting of methanolamine, ethanolamine, propanolamine, 1-amino-2-propanol, 1-amino-2-butanol, 1-amino-3-butanol and 4-amino-1-butanol.

8. A film-forming composition comprising the triazine ring-containing hyperbranched polymer of claim 1 .

9. The film-forming composition according to claim 8 , further comprising a crosslinking agent.

10. The film-forming composition according to claim 9 , wherein the crosslinking agent is at least one compound selected from among compounds containing a blocked isocyanate group and polyfunctional isocyanate compounds.

11. The film-forming composition according to claim 8 , further comprising a metal oxide.

12. The film-forming composition according to claim 11 , wherein the metal oxide is ZrO 2 .

13. A film comprising the triazine ring-containing hyperbranched polymer according to claim 1 .

14. A film obtained from the film-forming composition of claim 8 .

15. An optical member comprising a base material and the film of claim 13 or 14 formed on the base material.
