Abstract: The present disclosure provides a non-hydrocarbyl-based alcohol initiated polyetheramine. In particular, the polyetheramine of the present disclosure is produced from a tetrahydrofurfuryl alcohol-based initiator which is alkoxylated and then reductively aminated. The polyetheramine of the present disclosure may be used in a variety of applications, such as a raw material in the synthesis of a dispersant for use in an aqueous pigment dispersion.
Abstract: An extrudable polyvinyl chloride composition comprising from 80 to 99.9 percent by weight polyvinyl chloride for use in extruding a first part and a second part, wherein a fusion joint between the first extruded part and the second extruded part is formed by: A) composition at least a portion of a first terminal edge of the first extruded part and a first terminal edge of the second extruded part; B) engaging the melted terminal edges; and C) maintaining pressure between the engaged terminal edges to create a fused joint having a strength that is at least 50% of the tensile strength of the extruded part as measured by ASTM D638-2a. The extruded parts can be pipe sections.
