TEREPHTHALATE AND BENZOATE BASED ESTERS AND EPOXIDIZED OIL COMPOSITIONS

Abstract

The present invention provides a non-phthalate, highly sustainable plasticizer, with performance comparable to or better than the existing orthophthalate market leader (DINP) and non-phthalate market leader (DOTP) at a lower cost position. The novel plasticizers are terephthalate ester and epoxidized oil compositions and dibenzoate ester and epoxidized oil compositions. The novel plasticizer compositions are produced by blending a fast fusing terephthalate diester or dibenzoate ester with an epoxidized oil. The presence of the terephthalate diester or the dibenzoate ester in the blend imparts better physical properties and performance properties over the ester or epoxidized oil components alone.

Abstract

The invention provides a PVB interlayer sheet having a surface topography on at least one surface which is characterized as having a relatively low profile and a controlled, collapsible surface roughness profile (upon exposure to heat) having a population of significantly more surface peaks than negative peaks (valleys) in certain embodiments and slightly more distant peak spacing than is generally found in embossed PVB interlayers. The PVB interlayer sheets of the invention thus provide very good initial contact and tack of PVB to a glass surface, while leaving very little residual air behind after a first nip in a traditional glass lamination process when compared to other surface designs. The PVB interlayer sheets of the invention also exhibit a wide deairing window which affords greater tolerance of temperature and process variations.

Processing schemes are described herein for converting waste plastic (or hydrocarbon having recycled content derived from waste plastic) to recycle content alkanes by feeding a recycled-content pyrolysis gas stream to an unsaturated gas plant of a refinery complex and recovering recycled-content alkanes streams from the unsaturated gas plant.

Abstract

A process is disclosed for recovering soft poly(vinyl butyral) from a plasticized poly(vinyl butyral) multilayer sheet comprising stiff poly(vinyl butyral) and soft poly(vinyl butyral). The multilayer sheet, which may be scrap or recycled material, is first converted to a granulate form and then treated with plasticizer. This plasticizer treatment serves to remove the soft poly(vinyl butyral) component from the granulate, but thereby provides a varnish comprising the soft poly(vinyl butyral) mixed with excess plasticizer. This varnish is however highly viscous and thus difficult to handle or mechanically process. The present disclosure provides a solution to this handling problem by the addition of soft poly(vinyl butyral) having a lower concentration of plasticizer to the varnish, until a product is obtained having a sufficiently low concentration of plasticizer to render the product capable of mechanical processing, for example pelletizing. The resulting product can then be utilized to form soft poly(vinyl butyral) sheets, thereby improving the recyclability of scrap multilayer poly(vinyl butyral) materials.

Abstract

A dichloromethane-free wet spinning process for producing cellulose triacetate fiber with a silk factor greater than 8.0. A dichloromethane-free cellulose triacetate dope comprising dimethylacetamide is wet spun into a coagulation bath which is controlled to a temperature ranging from 20°C to 40°C and comprising dimethylacetamide and water. A jet draw stretching ratio ranging from 0.3 to 1.4 is applied to the wet spun CTA fibers which may also be subjected to one or more post jet draw stretching steps. During drying, the CTA fibers are partially or completely shrunk. This process enables CTA fiber(s) having a silk factor greater than 8.0 to be produced without using dichloromethane and without the energy costs associated with other processes that requiring lower or higher coagulation bath temperatures.
