Methods for preparing oriented polymer tubes, such as biodegradable polymer tubes suitable for in vivo use, are provided herein. The disclosed methods provide alternatives to the typical extrusion/expansion methods by which oriented polymeric tubes for such uses are commonly produced. Advantageously, the disclosed methods can provide more homogeneous molecular orientation of crystallizable polymers within the tube walls, which can endow such polymeric tubes with enhanced strength (e.g., resistance to compression) and toughness.

The invention provides an amorphous copolymerized polyester raw material for a film. The raw material contains ethylene terephthalate as a main constituent component, and contains from 18% by mol to 30% by mol of neopentyl glycol when a total amount of a glycol component in a total polyester resin component is taken as 100% by mol. The raw material contains from 8% by mol to 16% by mol of a constituent unit derived from diethylene glycol in the total amount (100% by mol) of the glycol component in the total polyester resin component. The raw material has an intrinsic viscosity of from 0.70 dl/g to 0.86 dl/g. The raw material has a melt viscosity of 200 Pa.Math.S or less, when measured at a shear rate of 6080/S at 250° C.

A downhole probe of a drilling rig has a probe sleeve for protecting the downhole probe. The probe sleeve may be made of a metal or a polymer such as polyphenylene sulfide. The probe sleeve may be heat-shrinkable to provide a tight fit between the downhole probe and the probe sleeve. The probe sleeve may include one or more protrusions shaped to engage a centralizer surrounding at least part of the downhole probe. The one or more protrusions may be arranged to prevent rotation of the centralizer relative to the probe sleeve. The probe sleeve may be made using a modified extrusion process and may include reinforcement to add strength to weld-lines along the length of the probe sleeve. The protrusions may also be used as reinforcement.

A multilayer composite is disclosed comprising a heat shrinkable polymer layer and a nanofiber layer. Methods of forming the composite and uses thereof are also described.
