A polymeric polyphosphite and copolymeric polyphosphite is described which contains a cycloaliphatic moiety, preferably cyclohexane dimethanol, in the polyphosphite backbone chain.

A tropicalizing agent including a liquid fat component and a plurality of gel beads that include a sugar or polyol in an amount of about 20 to 50 weight percent of the gel beads, an emulsifier component to facilitate uniform gel bead distribution, and the remainder being water present in an amount sufficient to ensure that the sugar or polyol is present in aqueous form. Preferably, the liquid fat component is present in an amount sufficient to disperse the gel beads therein and wherein a majority of the gel beads remain substantially intact for at least about 4 hours after being cooled below about 30° C. Methods of making tropicalizing agents and using the agents to tropicalize chocolate products or analogues thereof, as well as the resultant chocolate or chocolate analogue articles, are also included.

A polymeric polyphosphite and copolymeric polyphosphite is described which contains a cycloaliphatic moiety, preferably cyclohexane dimethanol, in the polyphosphite backbone chain. Incorporation of the polymeric polyphosphite into synthetic polymers reduces the yellowness index of any polymer into which the polymeric polyphosphite additive has been added, as well as increased hydrolytic stability as well as increased resistance to migration in food packaging.

This present invention discloses a waterborne polymer modified emulsified asphalt mixture and the preparation method thereof, and particularly relates to a waterborne polyurethane emulsified asphalt concrete, a waterborne acrylic resin emulsified asphalt concrete, and a waterborne epoxy resin emulsified asphalt micro-surfacing mixture, and preparation methods thereof. A mixture containing a waterborne polymer modified emulsified asphalt forms a high-performance composite system having a spatial network structure, and has good performance and simple preparation process.

The invention discloses a functionalized assembly magnesium-aluminum-based layered double hydroxyl metal hydroxide modifier and a preparation method thereof. The modifier uses an anionic antioxidant active ingredient to modify LDHs intercalation and surface modification It is prepared by organically modifying and co-functionalizing the assembly of agents. The present invention enhances its anti-thermal and oxidative aging ability by intercalating the active ingredients of anionic antioxidants into the interlayer of LDHs, and at the same time utilizes the laminate structure of LDHs to prevent anti- The oxygen agent migrates to the surface in the asphalt to improve the long-term effect of the antioxidant; by grafting the surface modifier of the long-chain branched organic functional group to the surface of the LDHs, the polar groups on the surface of the LDHs are reduced by the chemical interaction between the two. Inhibit the inter-particle agglomeration of LDHs and improve the dispersion of LDHs in asphalt. At the same time, the introduction of long-chain branched organic functional groups can enhance the lipophilicity of LDHs, enhance the compatibility and stability with asphalt, and significantly improve the thermal oxygen and UV aging resistance of asphalt. ability.

The invention discloses a SBS containing uniformly distributed butadiene blocks with a 1,2 structure and its hydride SEBS and a preparation and application method. The preparation process of the SBS is that styrene is polymerized by an initiator under the action of an activator, The second-stage polymerization process is to dissolve the 1,2 structure regulator in butadiene and evenly add it to the polymerization kettle within 16-18 minutes. After the addition is completed, it will react for another 8-12 minutes. The third-stage polymerization can be polymerized with styrene or Coupled with a coupling agent, the content of 1,2-addition units in the polybutadiene segment in the obtained SBS is 38-42% and uniformly distributed, and the SEBS obtained after hydrogenation is compatible and stable with naphthenic oil or white oil Good performance, low oil mobility in SEBS, high light transmittance, can be widely used in transparent elastic materials.

The invention discloses a functional auxiliary agent for a hot fog machine and its preparation and use method. The mass percentage of paraffin oil in the auxiliary agent is 75-94.5%, the mass percentage of a surfactant is 5-20%, and a hot fog density regulating substance The mass percentage is 0.5‑5%. The preparation method is as follows: adding surfactant into paraffin oil, stirring evenly, adding heat fog density regulating substance to prepare oil suspending agent, filtering to remove residue to obtain finished product. The method of use is: add 30-50 mL / 667mL of functional additive 2 Fully mix with fungicides or insecticides and pesticides in formulations such as emulsifiable concentrate, water emulsion, suspoemulsion, suspension, etc., press 300‑500mL / 667m 2 Supplement the amount of water to prepare emulsion, and use a hot fog machine for hot fog spraying to prevent and control crop diseases and insect pests.
