  • Patent number: 8614155
    Abstract: An enhanced prepreg for printed circuit board (PCB) laminates includes a substrate and a resin applied to the substrate. The resin includes a curable polymer and a polymerization initiator polymer having a backbone with a free radical initiator forming segment that breaks apart upon being subjected to heat to generate a plurality of non-volatile initiating species. This resin composition eliminates possible volatile loss of the free radical initiator during all processing steps in the preparation of PCB laminates. The resin may additionally include a cross-linking agent, flame retardant and viscosity modifiers. In one embodiment, a sheet of woven glass fibers is impregnated with the resin and subsequently dried or cured. The glass cloth substrate may include a silane coupling agent to couple the resin to the substrate. In another embodiment, resin coated copper (RCC) is prepared by applying the resin to copper and subsequently curing the resin.

  • Patent number: 8598281
    Abstract: An epoxybenzyl-terminated poly(arylene ether) has the structure R—W—R wherein W is a divalent poly(arylene ether) residue terminated with phenolic oxygen atoms, and R is an epoxybenzyl group, wherein each occurrence of R is the same or different. The epoxybenzyl-terminated poly(arylene ether) is formed by reacting a peroxide-containing reagent with a vinybenzyl-terminated poly(arylene ether). Also disclosed is a curable composition including the epoxybenzyl-terminated poly(arylene ether)s, a curing promoter, and, optionally, an auxiliary epoxy resin. The curable composition is useful for the preparation of composites, and in particular, composites used in manufacturing printed circuit boards.

  • Patent number: 8541505
    Abstract: A thermoplastic composition is prepared by melt blending a poly(arylene ether) and an other resin, where the poly(arylene ether) has a particular molecular weight distribution. The thermoplastic composition exhibits significantly increased melt flow compared to compositions containing poly(arylene ether)s with similar intrinsic viscosities but different molecular weight distributions. The increased melt flow facilitates preparation of the thermoplastic composition and subsequent article fabrication procedures.

  • Patent number: 8507638
    Abstract: Described are polyesters comprising (a) a dicarboxylic acid component comprising terephthalic acid residues; optionally, aromatic dicarboxylic acid residues or aliphatic dicarboxylic acid residues; 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues; and cyclohexanedimethanol residues. The polyesters have a desirable combination of inherent viscosity and glass transition temperature (“Tg”). The polyesters can have an inherent viscosity from 0.35 to 1.2 dL/g as determined in 60/40 (wt/wt) phenol/tetrachloroethane at a concentration of 0.5 g/100 ml at 25° C. and a Tg of 85 to 115° C. The polyesters may be manufactured into articles such as fibers, films, bottles or sheets.
