A melt blended composition comprising, in weight percent (wt %) based upon the weight of the composition: (A) 55 to 94.99 wt % of a thermoplastic polymer, (B) 5 to 44.99 wt % of a moisture curable polymer, and (C) 0.01 to 5 wt % of a moisture condensation catalyst exhibits enhanced rheological and mechanical properties as compared to a composition alike in all aspects save for the presence of a moisture curable polymer.

A melt blended composition comprising, in weight percent (wt %) based upon the weight of the composition: (A) 55 to 94.98 wt % of a thermoplastic polymer, (B) 5 to 44.98 wt % of a moisture curable polymer, (C) 0.01 to 5 wt % of a moisture condensation catalyst, and (D) 0.01 to 5 wt % of a foaming agent, exhibits enhanced foaming, rheological and mechanical properties as compared to a composition alike in all aspects save for the presence of a moisture curable polymer.

A double coating, curing method, cured coating, and kit are provided. A first layer of the double coating can be a first cure coating composition, which has a first hydroxy-functional resin, a first crosslinking agent, and a first catalyst. A second layer of a second cure coating composition can have a low hydrophilicity acrylic resin as a second hydroxy-functional resin, a second crosslinking agent, and a second catalyst. The first catalyst catalyzes crosslinking between the second hydroxy-functional resin and crosslinking agent, and not between the first hydroxy-functional resin and crosslinking agent. The second catalyst catalyzes crosslinking between the first hydroxy-functional resin and crosslinking agent, and not between the second hydroxy-functional resin and crosslinking agent. The first and/or second hydroxy functional resins can facilitate catalyst migration from one layer to the other. The separate compositions can be shelf-stable and/or the curing can occur at low temperature.

A long-acting super-hydrophobic coating resistant to water pressure impact and preparation method thereof. The long-acting super-hydrophobic coating includes a conductive substrate and the following raw materials in parts by weight: 1 part to 10 parts of titanium source or zinc source, 40 parts to 100 parts of deionized water, 20 parts to 50 parts of hydrochloric acid or 20 parts to 40 parts of sodium hydroxide, 1 part to 10 parts of electrolyte, 1 part to 10 parts of low surface energy modifier, 10 parts to 20 parts of high molecular polymer, 1 part to 5 parts of carbon nanotube and 70 parts to 100 parts of organic solvent. The long-acting super-hydrophobic coating has an organic-inorganic nano-interpenetrating network structure, which improves the stability of the multi-stage nano-micro structure, so that the super-hydrophobic coating surface has a good high-pressure water impact resistance and high-pressure static water resistance.

Provided are methods of producing sulfur- and phosphorus-containing polymers from beta-lactones. The sulfur- and phosphorus-containing polymers include bio-based sulfur- and phosphorus-containing polymers that may be obtained from renewable sources.

A composition includes a polycarbonate resin, a heat stabilizer, and an acid stabilizer. An article formed from the composition, when tested using a 2.5 mm color plaque, includes a level of free OH groups that is less than a level of free OH groups of a reference article injection molded from a substantially similar reference composition consisting essentially of the polycarbonate resin without the heat stabilizer and the acid stabilizer. Methods for forming the molded article in accordance with the above are also described.
