摘要:
Disposable absorbent articles comprising an absorbent material and a degradable thermoplastic polymer composition comprising an aliphatic polyester and an antimicrobial composition. The antimicrobial composition includes an antimicrobial component and an enhancer component. The aliphatic polyester and antimicrobial composition are formed into webs by melt extrusion, such as nonwovens and films, that are incorporated into disposable absorbent articles, such as disposable infant diapers, adult incontinence articles, feminine hygiene articles such as sanitary napkins, panty liners and tampons, personal care wipes and household wipes to provide odor control, control of microbial growth, and control of microbial toxin production.
摘要:
Antimicrobial compositions comprising aliphatic polyester, and an antimicrobial component effective for antimicrobial activity, and, in some embodiments, an enhancer. Example: blend of poly(lactic acid) polymer (55g) with propyleneglycol monolaurate antimicrobial component (9g), and benzoic acid enhancer (1g). Inventive resin compositions are effective against gram negative and gram positive bacteria, mold and mildew. Preferred compositions comprise materials that are GRAS (Generally Regarded As Safe).

摘要:
A composition that includes polylactide resin and plasticizer, the plasticizer having a chemical formula: wherein R may be the same or different and wherein at least one R is a branched alkyl group having a carbon chain length of C5 or greater; and R is an H or an acyl group. In another aspect, the invention provides a process for providing an semicrystalline polylactide film, the process including the steps of providing a polylactide composition that includes polylactide resin, nucleating agent, and the foregoing plasticizer. The composition is extruded as a molten sheet which is then cooled to crystallize the polylactide and provide the film.

The present invention provides an adhesive made from a reaction product of: (a) a polymerizable monomer derived at least in part from non-petroleum resources; (b) an initiator; (c) a polymeric stabilizer, wherein the reaction occurs in water to yield a microsphere adhesive. The microsphere adhesive can be formulated into a pressure sensitive adhesive composition that can be applied to various substrates such as paper and polymeric film to produce repositionable adhesive coated articles such as tapes, notes, flags, easels and the like.
摘要:
A photoactive compound that is the Michael addition reaction product of an aziridine compound and a photoinitiator-functional (meth)acrylate is described. The compound can be used to crosslink (meth)acrylic polymers via a hydrogen abstracting or an alpha-cleavage mechanism.
摘要:
An adhesive composition comprising an emulsion polymer which comprises a (meth)acrylate copolymer, and aziridinyl silane and an optional silica particle component is described. The addition of the aziridinyl silane results in a significant increase in the shear properties, particularly at elevated temperatures.
