Abstract

The disclosure aims to provide a composition capable of suppressing fluororesin agglomeration, which may lead to strands with a poor appearance, even when the proportion of the fluororesin is increased, and also aims to provide a molded article, a laminate, and a resin. The disclosure relates to a composition containing: a fluororesin A; and a resin B other than the fluororesin A, the resin B having a melt flow rate of 30 g/10 min or higher at a melting point +12° C., at least one of the fluororesin A or the resin B containing a group (I) represented by the following formula:wherein R1 and R2 are the same as or different from each other, are each hydrogen or an organic group, and optionally bond to each other to form a ring structure; and a double line composed of a solid line and a dotted line represents a single bond or a double bond.

First claim

1 . A composition comprising:
a fluororesin A; and a resin B other than the fluororesin A, the resin B having a melt flow rate of 30 g/10 min or higher at a melting point +12° C., at least one of the fluororesin A or the resin B containing a group (I) represented by the following formula:

wherein R 1 and R 2 are the same as or different from each other, are each hydrogen or an organic group, and optionally bond to each other to form a ring structure; and a double line composed of a solid line and a dotted line represents a single bond or a double bond.

2 . The composition according to claim 1 ,
wherein at least one of the fluororesin A or the resin B has a thermal decomposition temperature of 330° C. or higher.

3 . The composition according to claim 1 or 2 ,
wherein the fluororesin A includes at least one selected from the group consisting of polytetrafluoroethylene, a tetrafluoroethylene/perfluoro(alkyl vinyl ether)copolymer, and a tetrafluoroethylene/hexafluoropropylene copolymer.

4 . The composition according to any one of claims 1 to 3 ,
wherein the resin B includes at least one selected from the group consisting of a liquid crystal polymer, polyetherimide, polyphenylene sulfide, polyaryl ether ketone, polysulfone, and polyethersulfone.

5 . The composition according to any one of claims 1 to 4 ,
wherein the fluororesin A is contained in an amount of 10% by volume or more.

6 . The composition according to any one of claims 1 to 5 ,
wherein the group (I) is an oxazoline group.

7 . The composition according to claim 6 ,
wherein the oxazoline group is derived from an oxazoline compound.

8 . A molded article comprising the composition according to any one of claims 1 to 7 .

9 . The molded article according to claim 8 , which is intended to be used for a dielectric material.

10 . A laminate comprising:
metal foil; and the molded article according to claim 8 or 9 .

11 . The laminate according to claim 10 ,
wherein the metal foil comprises copper.

12 . A resin comprising a group (I) represented by the following formula and having a thermal decomposition temperature of 330° C. or higher:

wherein R 1 and R 2 are the same as or different from each other, are each hydrogen or an organic group, and optionally bond to each other to form a ring structure; and
a double line composed of a solid line and a dotted line represents a single bond or a double bond.

13 . The resin according to claim 12 , further comprising an amide group and an ester group.

14 . The resin according to claim 12 or 13 ,
wherein the group (I) is an oxazoline group.

15 . The resin according to claim 14 ,
wherein the oxazoline group is derived from an oxazoline compound.

16 . The resin according to any one of claims 12 to 15 ,
wherein the resin has a melt flow rate of 30 g/10 min or higher at a melting point +12° C.

17 . The resin according to claim 16 ,
wherein the resin is a liquid crystal polymer, polyetherimide, polyphenylene sulfide, polyaryl ether ketone, polysulfone, or polyethersulfone.

18 . The resin according to any one of claims 12 to 15 ,
wherein the resin is a fluororesin.

19 . The resin according to claim 18 ,
wherein the fluororesin includes at least one selected from the group consisting of polytetrafluoroethylene, a tetrafluoroethylene/perfluoro(alkyl vinyl ether)copolymer, and a tetrafluoroethylene/hexafluoropropylene copolymer.

20 . The resin according to claim 18 or 19 ,
wherein the fluororesin is insoluble in an aprotic solvent.

21 . The resin according to claim 20 ,
wherein the aprotic solvent includes at least one selected from the group consisting of a perfluorinated aromatic compound, a perfluorinated trialkylamine, a perfluorinated alkane, a hydrofluorocarbon, a perfluorinated cyclic ether, a hydrofluoroether, and an olefin compound containing at least one chlorine atom.

22 . The resin according to any one of claims 12 to 21 ,
wherein the resin is a resin modifier.
