Polymeric compositions useful for use with solid or liquid phosphate fertilizers include one or more first copolymers having at least two repeat units selected from maleic, itaconic, and sulfonate repeat units, and one or more second copolymers having maleic and olefinic repeat units. The compositions are capable of synergistically reducing or eliminating phosphate fixation, and are relatively low in cost. The compositions may also be supplemented with product-marking dyes and second copolymers having high and low molecular weight profiles in order to control fines or dust during handling and application of solid phosphate fertilizers.

The present invention relates to modified polysaccharide-based self-assembled aggregates capable to encapsulate and deliver active agents into and between media of different hydrophilicity/hydrophobicity.

Hybrid microparticle having a polymer core and a shell which surrounds the polymer core at least in sections and which has a silicon dioxide layer; characterized by an RF value, the RF value being defined as the ratio of an external surface area amenable to the adsorption of nitrogen to a surface area which is computable from an arithmetic mean diameter of the hybrid microparticle considered as an ideal sphere, where the shell has a structure selected from: closed and smooth, with the shell having an RF value of between 1 and 1.5; closed and hillocky, with the shell having an RF value of between 1.51 and 3; or open, with the shell having an RF value of greater than 3.01.

In a process for producing a (poly) sulfide compound represented by General Formula (2) of the present invention, thiol compounds represented by General Formula (1) are reacted with each other in the presence of a basic compound represented by General Formula (4) or General Formula (5) and sulfur. ##STR00001##

A door assembly. The door assembly may include at least one door panel and a door frame having a plurality of frame members including a header and a pair of side jambs. The invention may also be considered a frame member. The frame member may include a core; and a two-piece top piece adjoining the core to form a structural member. The core and the top piece may be a composite of cellulosic material and at least one other material. The door assembly may further include at least one adjacent panel. Also disclosed are door jamb frame members and mullion frame members.

The invention relates to a curable resin that represents an excellent substitute for phenolic resins and is therefore able to replace phenolic resins in all applications in which they are used. Said resin is characterised in that it comprises: (1) at least one prepolymer resulting from the prepolymerisation of a compound A comprising at least one aromatic or heteroaromatic ring, a first group OCH2-CCH and at least one second group selected from the groups OCH2-CCH2 and CH2-CHCH2, said groups being carried by the at least one aromatic or heteroaromatic ring; and (2) a compound B comprising at least two thiol groups (SH). The invention also relates to a material obtained by curing said curable resin, and in particular to an ablative composite material. The invention further relates to a material obtained by curing said curable resin.

Are disclosed a thermoplastic material for vehicle interior or exterior having not only excellent strength in winter but also excellent sound-absorption and heat-resistance, a method for preparing the same and an article for vehicle interior or exterior using the same. A method for producing a thermoplastic material for interior or exterior of vehicle, comprising the steps of: forming a fiber sheet or web by randomly arranging fibers having a length of 50 mm or more, the fibers being selected from the group consisting of glass fibers, carbon fibers, basalt fibers, aramid fibers and mixtures thereof; applying polyethylene powders to one side or both sides of the fiber sheet or web; forming a fiber reinforced mat by heating and pressing the fiber sheet or web to which the polyethylene powders are applied; and laminating the fiber reinforced mat on one side or both sides of a polypropylene base.

The present invention relates to (halogenated) copolymer vulcanizates and the use thereof in devices such as seals, tank linings, o-rings or hoses which are in contact with liquid medium comprising oxymethylene ether.

A curable silicone composition comprising: (A-1) a linear polysiloxane having DP from 25 to 10,000 and comprising from 2-25 R groups; (A-2) a resin type polysiloxane containing units having structures (R.sub.3SiO.sub.1/2).sub.a, (RSiO.sub.3/2).sub.b, and (RSiO.sub.3/2).sub.c where R is alkyl, and R is alkenyl; where a+b+c is from 0.90 to 1, and 0.2<a<0.5, 0.2<b<0.7, 0.02<c<0.3; (B) a crosslinker; and (C) 0.1-20 ppm of a hydrosilylation catalyst contained in a polysiloxane.
