Abstract
A curable composition includes particular amounts of a hydrogenated block copolymer having terminal reactive groups, a polymeric reactive diluent having a glass transition temperature of greater than or equal to 100° C. and at least one crosslinkable reactive group, and a filler. The curable compositions can provide corresponding cured compositions which can be useful in applications including build-up films, polytetrafluoroethylene (PTFE) replacement materials, and filled laminate core materials.
Claims15
A curable composition comprising:
- 1 to 25 weight percent of a hydrogenated block copolymer comprising at least one A block and at least one B block, wherein prior to hydrogenation, each A block is a polymer of a first vinyl aromatic compound, and each B block is a copolymer of a second vinyl aromatic compound, a conjugated diene, and optionally a third vinyl aromatic compound;
- 0.1 to 20 weight percent of a polymeric reactive diluent having a glass transition temperature of greater than or equal to 100° C. and at least one crosslinkable reactive group;
- and
- 50 to 90 weight percent of a filler;
- wherein weight percent of each component is based on a total weight of dry components of the curable composition.
