Provided is a process for preparing a PVDC additive blend in which an additive is blended with PVDC under high shear blending to produce a highly uniform blend in which the additive is homogeneously distributed throughout the PVDC. It has been found that performing high shear blending in multiple successive stages in which the concentration of the additive in the blend is reduced in each successive stage helps in prove the uniformity of the PVDC additive blend. For example, the high shear blending may be carried out in 2 to 6 stages, and in particular, from 2 to 4 stages. Also provided is a PVDC additive blend having a uniform blend of PVDC and an additive, such as a blend of a PVDC copolymer of vinylidene chloride and methyl acrylate and a fluorescing agent, such as 2,2′(2,5-thiophenylendiyl)bis(5-tert-butylbenzoxazole).

Provided is a resin mixture containing two kinds of polycarbonate particles having different weight average molecular weights, wherein a melt flow rate (MFR-1) of a blended material of the polycarbonate particles and a melt flow rate (MFR-2) of a kneaded material of the polycarbonate particles satisfy the following relation (1), Relation (1): MRF-2<MRF-1, provided that MRF-1 and MRF-2 are measured using a melt flow rate (MRF) measuring apparatus under conditions of a temperature 300° C. and a load of 1.2 kg.

Provided herein is a method for preparing antimicrobial thermoplastic resins and products thereof.

The present invention relates to a process comprising the step of contacting an aqueous dispersion of swelled polymer particles with a rheology modifier and a binder to form a coatings composition with a VOC of less than 50 g/L. The swelled polymer particles arise from neutralization of alkali swellable polymer particles having a high acid core content and a low T.sub.g shell. The composition arising from the process of the present invention is useful for improving open time, especially for low VOC coatings applications.

Provided is a method of producing a composite resin material that has excellent shapeability and enables supply of a shaped product having good properties. The method of producing a composite resin material includes: a mixing step of mixing a fluororesin, fibrous carbon nanostructures, and a dispersion medium to obtain a slurry; and a formation step of removing the dispersion medium from the slurry and forming a particulate composite resin material. The particulate composite resin material has a D50 diameter of at least 20 μm and not more than 500 μm and a D90 diameter/D10 diameter value of at least 1.2 and not more than 15. The D10 diameter, D50 diameter, and D90 diameter are particle diameters respectively corresponding to cumulative volumes of 10%, 50%, and 90% calculated from a small particle end of a particle diameter distribution of the particulate composite resin material.

An amorphous or semi-crystalline polymer/aPHA composition (masterbatch) has a high load of aPHA (30 to 50 wt % based on the total amount of the composition). A method for production of the composition includes two or more split feedings of the aPHA in a blending or mixing or compounding operation. The method includes feeding about 1-15 weight percent (wt %) of the total aPHA in a primary feed hopper of a blending or mixing or compounding apparatus and about 30-49 weight percent downstream in the process.

A polyethylene composition having increased environmental stress crack resistance (ESCR) is comprised of a polymer blend of a high density polyethylene (HDPE) and polyethylene glycol (PEG). The PEG is present in the polymer blend in an amount of from 0.5 wt. % to 15 wt. % by total weight of the polymer blend. The PEG may have an average molecular weight of from 2000 to 40,000. In a method of forming a polyethylene composition having increased ESCR, a HDPE is modified by combining the HDPE with PEG in a polymer blend, the PEG being present in an amount of from 0.5 wt. % to 15 wt. % by total weight of the polymer blend. The polymer blend can be formed into an article of manufacture, such as a bottle cap.

The present disclosure is directed to examples of housing for a luminaire. In one example, the housing includes a bioplastic base formed to receive a light emitting diode and a driver and a lens coupled to the bioplastic base. The bioplastic base may include a bioplastic and is formed with a non-biodegradable or a biodegradable plastic.

Provided is an ethylene-based modifier with which a film having good slipperiness and relatively less fish eyes can be formed. The ethylene-based modifier has a strain-hardening exponent of 0.27 or more and 0.53 or less as determined by the LAOS method.
