An epoxy functional acrylic resin having a T.sub.g of greater than 85° C. and a calculated solubility parameter from about 9.20 to about 9.30 (cal/cm.sup.3).sup.1/2, powder coating compositions including the same and coated substrates coated with the powder coating composition is described. The resin includes, as copolymerized monomers, from about 10 wt. % to about 40 wt. % of one or more epoxy functional unsaturated monomers; from about 10 wt. % to about 20 wt. % of one or more hydrophobic acrylic monomers, and from greater than 50 wt. % to about 75 wt. % of at least one nonionic copolymer that is different from the hydrophobic acrylic monomers ii), each monomer wt. % based on the total weight of copolymerized monomers in the resin.

The invention provides a method of preparing an electrically conductive polymeric material. The method comprises providing a polymeric network having a short chain conductive polymer dispersed in the polymeric network and electropolymerising a conductive polymer within the polymeric network. Also described is a free standing flexible electrically conductive polymeric material comprising a conductive polymer within a polymeric network.

Disclosed are: a polyalkylene terephthalate resin composition comprising (A) a polyalkylene terephthalate resin and (B) an acrylic-based core-shell polymer which has an average particle size of 2 μm or greater and in which an amount of the core layer component is more than 80% by mass but less than 100% by mass relative to a total mass of the core layer component and a shell layer component; and a molded article which is obtained by molding the polyalkylene terephthalate resin composition.

Crosslinkable compositions, crosslinked compositions, articles containing these compositions, and methods of making the articles are provided. The crosslinkable compositions, which include two (meth)acrylate copolymers plus a tackifier, are used to form the crosslinked compositions upon exposure to ultraviolet radiation. The crosslinked compositions can function as pressure-sensitive adhesives. The crosslinkable compositions are well suited for use with hot melt processing methods.

Disclosed is a coating agent composition comprising (A) a polytetrafluoroethylene resin emulsion, (B) an urethane resin emulsion, and (C) a hydrogenated NBR emulsion, and preferably further comprising (D) an acrylic resin emulsion and/or an ethylene-vinyl acetate copolymer resin emulsion. When this coating agent composition is used as a surface coating agent for general vulcanized rubber-molded products, evaluation of adhesion to rubber by an adhesion test is hardly impaired, and bleeding evaluation, evaluation of the flexibility of the coating agent by a bending test, and evaluation of the reduction in adhesion to rubber due to bloom from the rubber by a high-temperature and high-humidity test are all satisfied.

A transparent, heat-sealable coating for transparent PET packaging foils can be provided by using a heat-sealable lacquer based on styrene-containing copolymers, on poly(meth)acrylates, on at least one polyester and optionally on a tackifier, and also the process for the sealing of a foil coated with this lacquer. It is surprising here that, despite the use of a rubber based on styrene-containing polymers that is not optically compatible with polyesters and polymethacrylate, the transparency of the heat-sealable coatings is still very high.
