  • Patent number: 6573330
    Abstract: A process for preparing a water-absorbent resin is provided which enables the water-absorbent resin to ensure the reduction in the release amount of liquid and the increase in the liquid diffusibility. In the preparation process, the water-absorbent resin is prepared by polymerization of a water-soluble ethylenic unsaturated monomer. The polymerization of the water-soluble ethylenic unsaturated monomer is allowed to take place in the presence of a water-absorbent resin having a water-absorbing rate different from that of a water-absorbent resin resulting from polymerization of the water-soluble ethylenic unsaturated monomer. In a preferred mode, the polymerization is performed by a reversed-phase suspension polymerization method.

  • Patent number: 6492462
    Abstract: The rheological properties of a crosslinkable resin system are modified by the presence of a side chain crystalline (SCC) polymer (or a similar crystalline polymer which melts over a narrow temperature range). The polymer dissolves in the curable system at temperatures above the melting point of the crystalline polymer (Tp), but when the system is then cooled to a temperature below Tp, at least partially forms a separate phase in the curable system. Below Tp, this separate phase substantially increases the viscosity of the curable system (i.e. makes it thicker than the same system without the crystalline polymer). This is particularly valuable for sheet molding composites (SMCs) in which the increase in viscosity makes the composites less tacky, and for dry film resists (DFRs). Above Tp, the curable system containing the dissolved crystalline polymer has a viscosity which is substantially less than its viscosity below Tp.

Preferably the hard phase (a1) may contain low molecular weight and/or polymer-bound UV-absorbers. The difference between index of refraction of the thermoplastic polymer A and that of the thermoelastic polymer B is at most 0.02. Despite its matte finish, the film has high transparency, is weather resistant, has low incidence of white fracture when buckled or folded, and has impact strength which does not degrade upon cooling or heating.

  • Patent number: 6337374
    Abstract: There is a need for halogen-free polymeric compositions for utilization in gaskets and seals that offers high tensile strength and high tear strength as well as good resistance to compression set. Seals for automotive body applications, such as, windows, hoods, trunks, and doors, and building applications, such as window glazing gaskets and weather strips, should be dimensionally stable, provide low compression set, and offer outstanding sealing characteristics over a broad temperature range. They must be capable of sealing out noise, wind and water, while providing long-term ultraviolet light resistance.
