A curable composition includes a condensation product having a weight average molecular weight of 30,000 or less and a curing agent, the condensation product being obtained by hydrolysis and condensation of a first and secondsilane compound in the presence of a neutral salt catalyst. The condensation product also has a ratio Y/X of 0.2 or less, wherein X is the number of moles of an OR.sup.3 group directly bonded to silicon atoms of the first and second silane compounds, and Y is the number of moles of an OR.sup.3 group directly bonded to a silicon atom of the condensation product. The first silane compound is represented by R.sup.1—(SiR.sup.2.sub.a(OR.sup.3).sub.3-a), and the second silane compound is represented by R.sup.4—(SiR.sup.2.sub.a(OR.sup.3).sub.3-a).

The present invention relates to a plastic film and a method for manufacturing same. A plastic film, which is formed such that at least one part has a curved shape, can have high hardness, impact resistance, scratch resistance and high transparency. The plastic film is light and will not be easily damaged by external pressure and thus can substitute for the existing glass and is expected to be used for various electronic products such as a display and the like. In particular, the plastic film has at least one part in a curved shape and thereby is expected to be used for products in various shapes which cannot be manufactured by means of the existing glass. Moreover, a method for manufacturing a plastic film enables manufacturing of a plastic film having at least one part in a curved shape without curls or cracks as well as simultaneous performing of heat molding and heat curing, thereby increasing the productivity of a plastic film.

The present disclosure relates to a polycarbonate resin and a method of preparing the same, has an effect of providing a polycarbonate resin having superior chemical resistance and wear resistance due to application of a predetermined comonomer thereto, and a method of preparing the same.

An electroconductive resin composite includes an impact modifier domains and an electroconductive fillers dispersed therein. The domains are dispersed in a matrix in the form of a domain having an average particle size of 5 μm or less. The electroconductive fillers are dispersed in the matrix or at an interface between the matrix and the domains to form a network.

A polyalkylene carbonate resin composition with interpenetrating network structure includes an aliphatic polycarbonate obtained through a reaction of carbon dioxide with at least one epoxide compound selected from the group consisting of (C2-C10)alkylene oxide substituted or unsubstituted with halogen or alkoxy, (C4-C20)cycloalkylene oxide substituted or unsubstituted with halogen or alkoxy, and (C8-C20)styrene oxide substituted or unsubstituted with halogen, alkoxy, alkyl or aryl, at least one compound selected from a polyol compound, an epoxy compound and an acryl compound, and a curing agent for polymerization or networking.

The present invention addresses the problem of providing a resin having a high Abbe number and a small difference in hygroscopic expansion coefficient with respect to a polycarbonate resin having a low Abbe number and a high refractive index. The above problem can be solved by a polycarbonate resin including structural units represented by general formula (1). In general formula (1), R represents H, CH.sub.3, or C.sub.2H.sub.5.
