The present invention relates to a halogen-free resin composition, a prepreg and a laminate prepared therefrom. The halogen-free resin composition comprises, based on the weight parts of organic solids, (A) from 40 to 80 parts by weight of allyl-modified benzoxazine resin, (B) from 10 to 20 parts by weight of hydrocarbon resin, (C) from 10 to 40 parts by weight of allyl-modified polyphenyl ether resin, (D) from 10 to 20 parts by weight of allyl-modified bismaleimide resin, (E) from 0.01 to 3 parts by weight of an initiator, (F) from 10 to 100 parts by weight of a filler, and (G) from 0 to 80 parts by weight of a phosphorus-containing flame retardant. The prepreg and laminate prepared from the halogen-free resin composition have lower dielectric constant and dielectric loss tangent value, higher peel strength, high glass transition temperature, excellent thermal resistance and better flame retardant effect.

A golf ball resin composition contains a base resin for which, in dynamic viscoelasticity measurement, the storage modulus of the base resin measured at 23° C., 15 Hz and 1.0% strain, and tan δ determined under the same conditions, satisfy specific values; and for which the storage modulus of the base resin measured at 23° C., 15 Hz and 10% strain, and tan δ determined under the same conditions, satisfy specific values. By using this resin composition as a golf ball cover material, the force delivered to the ball while the ball and the clubface are in contact from impact to follow-through is more easily felt, facilitating distance control of the ball. Controllability with a short iron such as a sand wedge around the green is also excellent.

A resin composition, comprising the following components: (a) a thermal-curable resin system, which has a dielectric loss (Df) of not higher than 0.004 at 10 GHz; and (b) an alkenyl phenoxy phosphazene component, wherein the amount of the component (b) is 1 wt % to 30 wt % based on the total weight of the resin system (a) and the component (b).

Provided is a binder composition for a secondary battery electrode that can cause a secondary battery to display excellent rate characteristics and cycle characteristics. The binder composition for a secondary battery electrode contains a first particulate polymer having a core-shell structure including a core portion and a shell portion that partially covers an outer surface of the core portion.

A modified silica comprising organic molecules absorbed on the surface of a precipitated silica is provided. The modified silica is particularly suitable for use as filler in elastomeric mixtures as it provides improvement in the processing of the silica/elastomer mixtures. A process for preparing the precipitated silica is also provided.
