摘要:
Injection stretch blow molded (ISBM) articles containing a bio-based polymers and methods of forming the same are described herein. The method generally includes providing a propylene-based polymer; contacting the propylene-based polymer with polylactic acid to form a polymeric blend; injection molding the blend into a preform; and stretch-blowing the preform into an article.
摘要:
Polymeric compositions and processes of forming the same are discussed herein. The processes generally include contacting a polylactic acid with a reactive modifier selected from epoxy-functionalized polybutadiene, ionic monomer, and combinations thereof.
摘要:
Polymeric compositions and processes of forming the same are described herein. The processes generally include contacting a polyolefin with a polylactic acid in the presence of at least 800 ppm of radical initiator under extrusion conditions to produce a polyolefin-polylactic acid copolymer.
摘要:
A high melt strength polypropylene is formed using maleated polypropylene and a combination of coupling agents and acid neutralizers. The maleated polypropylene can be formed using multi-functional monomers. The high melt strength polypropylene can be useful for foaming, sheet extrusion thermoforming, extrusion blow molding, extrusion coating, fiber, film, and the like.

摘要:
Films and processes of forming the same are described herein. The processes generally include providing a propylene-based polymer; contacting the propylene-based polymer with polylactic acid in the presence of a modifier to form a polymeric blend, wherein the modifier is selected from epoxy-functionalized polyolefins, maleic anhydride modified polyolefins, ethylene-methacrylate copolymers, styrene-ethylene-butadiene-styrene (SIBS) polymers, and combinations thereof; forming the polymeric blend into a film; and monoaxially orienting the film.
摘要:
Crosslinkable silane-grafted polypropylene compositions and processes of forming the same are described herein. The processes generally include contacting a polyolefin, a multifunctional monomer and a silane compound in the presence of a radical initiator, wherein the polyolefin is selected from polypropylene, polyethylene, combinations thereof and copolymers thereof.
摘要:
Fibers and methods of forming the fibers are described herein. The fibers generally include an ethylene based polymer exhibiting a molecular weight distribution of from about 2 to about 8.
