    Abstract: Toughened thermosetting resins comprising thermosetting resins and rubber particles having an average particle size in the range of 20 to 500nm. The toughened resins are obtained by mixing a fully vulcanized powdery rubber having an average particle size in the range of 20 to 500nm with thermosetting resin prepolymers and then curing them. The toughened thermosetting resins comprise rubber phases having a small, uniform and stable particle size, which results in a very significant toughening effect, especially when crazes rapidly grow (as in a standard Izod impact test). The toughened thermosetting resins are excellent in impact resistance, strength, modulus and heat resistance, and when appropriately toughened, the thermosetting resins can be enhanced in terms of impact strength, glass transition temperature and heat distortion temperature.

  • Patent number: 6093762
    Abstract: A vehicle for lithographic printing ink is prepared by using an improved binder resin of petroleum resin-modified phenol resin, in which the melt viscosity of the binder resin is maintained below a certain level to improve the workability in polymerization process and the misting in printing press is reduced by using the improved binder resin. In the preparation of the binder resin, acid modified hydrocarbon resin (A) is prepared by reacting components (a) mainly comprising five-membered cyclic compounds or their Diels-Alder reaction products with the components (b) comprising unsaturated carboxylic acids or their anhydrides, and said acid modified hydrocarbon resin (A) is then reacted with phenol resin (B) in which portions of the phenol resin are fed one after another, thereby producing said binder resin having the properties of: high weight average molecular weight, low melt viscosity and low ratio of melt viscosity to solution viscosity.

  • Patent number: 5952425
    Abstract: Phenolic resin curatives having a majority of dibenzyl ether linkages were unexpectedly found to be very effective in curing unsaturated rubbers in a blend of a crystalline polyolefin and said rubber. Their effectiveness exceeds that of conventional phenolic resins for many thermoplastic vulcanizate compositions allowing for the reformulation of the recipes with lower amounts of curatives and equivalent or superior physical properties in the resulting thermoplastic vulcanizate.

  • Patent number: 5936038
    Abstract: A vulcanizable elastomer having at least one pendant reactive amino group. The elastomer is vulcanized by using a phenolic-resin curative essentially in the absence of an activation catalyst, to form a vulcanizate. Also provided is a thermoplastic elastomeric vulcanizable composition of matter, employing the elastomer having the pendent reactive amino group, which may be dynamically vulcanized without the use of an activation catalyst. Further provided is a method for vulcanizing an elastomer having at least one pendent reactive amino group by utilizing a phenolic vulcanizing agent without the use of a catalyst.

  • Patent number: 5912317
    Abstract: An improved oxazolidine-based hardener to be used with a resorcinol resin or a tannin resin as the adhesive for the bonding of wood articles. Preferably, an oxazolidine is combined with particulate silica, and the resin is combined with a base such as NaOH. The adhesive based on the improved hardener can be used to glue wood particles to pass wet strength requirements after the glue is cured at room temperature for under 24 hours. The improved hardener composition is storage stable; it can be prepared anytime before its use and, thus, eliminate the need to prepare a hardener immediately prior to the glue use. Since it is formaldehyde-free; it eliminates the safety issues associated with handling formaldehyde or paraformaldehyde. Also, the hardener provides flexible gel time or working time. Since the resins can be cured at room temperature, heating in an oven is not needed but could be used to reduce curing time. If radio frequencies are used to cure the resins, the exposure time can be reduced.

  • Patent number: 5677373
    Abstract: Process for producing a dispersion, wherein dispersed slightly crosslinked polyvinyl seed particles are swollen with an ionizing liquid, said seed particles containing covalently linked ionizable groups causing a swelling of the seed particles by the ionizing liquid to form a dispersion of droplets, wherein the resulting droplets after the swelling have a volume which is at least five times that of the seed particles. Said ionizing liquid may be or contain a polymerizable monomer or be charged with such a monomer. Polymerization of the monomers is effected in the droplets during or after the swelling, to form polymer particles.
