A low dielectric resin composition comprises a low dielectric resin containing acid anhydride, an epoxy resin, a rigid cross-linking agent, a soft cross-linking agent, and an accelerator. Such low dielectric resin can be dissolved in organic solvent more easily than a low dielectric resin without acid anhydride, and the low dielectric resin containing acid anhydride has a better compatibility with other organic components than a low dielectric resin without acid anhydride. A low dielectric resin composition with lower dielectric constant and better properties can thus be obtained. A film and a circuit board using such resin composition are also provided.

The present disclosure relates to a A method for manufacturing a crosslinked polyolefin separator and the crosslinked polyolefin separator obtained by the method are provided. The method includes (S1) mixing polyolefin, a diluting agent, an initiator and alkoxysilane containing a carbon-carbon double bonded group to an extruder, and then carrying out extrusion to obtain a silane-grafted polyolefin composition; (S2) molding and orienting the extruded silane-grafted polyolefin composition in the form of a sheet; (S3) introducing the oriented sheet to an extraction water bath containing a crosslinking catalyst to extract the diluting agent and perform aqueous crosslinking; and (S4) thermally fixing a resultant aqueous crosslinked product. The method can provide a separator having a high meltdown temperature and improved heat shrinkage.
