The present invention relates to a foam made of a specific material having superior properties and to cosmetics comprising said foam.

The present disclosure provides methods of improving adhesion of a non-di-(2-ethylhexyl)phthalate (DEHP) plasticized polyvinyl chloride (PVC) to an acrylic-based polymer or an ABS-based polymer. Such methods may comprise blending the acrylic-based polymer or ABS-based polymer with an impact modifier so that a rubber content in the acrylic-based polymer or ABS-based polymer is greater than 12% (w/w). Also provided are components of a device (e.g., a medical device) made by the disclosed methods.

Various coating compositions are described which provide protection for polymeric films and particularly PVC films. The coating compositions include particular resin(s) and opacifying agents. Also described are coated films utilizing the compositions and methods of forming the coated films.

Processes and facilities for using one or more PET-containing materials as a feedstock to a chemical recycling facility, and in particular a solvolysis facility, are provided herein. The PET-containing materials used as feedstock may comprise a quantity of PET and PVC-containing reclaimer flake reject. The PET and PVC-containing reclaimer flake reject may be derived from various plastic reclaimer separation processes, including density separation. Such flake reject materials are generally undesirable or unusable to mechanical PET recycling facilities due to the PVC content, and typically are sent to landfills and/or incinerators. However, the processes and facilities described herein make use of the PET and other plastics present in these otherwise undesirable or unusable flake reject materials.

The present invention relates to coatings for devices such as medical devices that are useful for coating a variety of different types of material surfaces, including polymer and metal surfaces. The present invention also includes the method of using the coated device and methods to make the coated device and coating.

The present invention relates to an acrylic processing aid, a method for preparing the same, and a polyvinyl chloride resin composition comprising the same. More specifically, the present invention relates to an acrylic processing aid having a core-shell structure comprising the core and shell comprise a polymer prepared by copolymerizing a methyl methacrylate monomer and an alkyl acrylate monomer having 1 to 18 carbon atoms, and wherein the core comprises the polymer having a weight-average molecular weight ranging from 10,000,000 to 18,000,000 g/mol, a method for preparing the same, and a polyvinyl chloride resin composition comprising the same.

Disclosed herein is a method to recover constituent polymers in multilayer plastic films or mixed plastic wastes. The method comprises selectively dissolving a polymer in a solvent at a temperature, wherein the polymer is soluble, but other polymers in the multilayer plastic film or mixed plastic waste are not. The solubilized polymer is then separated from the multilayer plastic film or mixed plastic waste by mechanical filtration and precipitated by changing the temperature and/or adding a cosolvent. The process is repeated for each of the polymer component, resulting in a number of segregated streams that can then be recycled. Computational tools can be used to select solvent systems and temperatures that selectively dissolve different polymers from among all of the components.

A method of preparing a foamed thermoplastic polymer comprises contacting a chemical blowing agent (A) which is a semi-carbazide with a thermoplastic polymer or a precursor of a thermoplastic polymer. Blowing agent (A) is preferably p-toluenesulfonyl semi-carbazide and said polymer is preferably PVC. Formulations, including liquid formulations which include the blowing agent (A) and other ingredients, are also described.

An oven-hardening modeling material, at least including a binder and a softener, the binder and the softener being in the form of a plastisol, the plastisol being essentially composed of PVC and plasticizer and the mass having an overall plasticizer content of 32 to 60 wt. %.

A method for producing molding compounds, at least including a binder and a softener, the binder and the softener being in the form of plastisols, the plastisol being essentially composed of PVC and softener, the method of production has the following steps: in a first step, mixing the PVC powder and the amount of softener with optionally other admixtures and/or additives and carrying out the mixing process at a mixing temperature of approximately 55 to 70° C.
