The present invention generally relates to an eco-friendly wearable article comprising a nutrient complex capable of efficiently able to reduce or eliminate methane gas emission during biodegradation of the article, and a method of making the eco-friendly wearable article containing the nutrient complex. Preferably, the nutrient complex typically comprises anionic sulphate ions and cationic salts of iron(II) and copper(II), thereby facilitating methane oxidation in an anaerobic environment such as a landfill.

An exemplary embodiment provides a method for preparing a latex composition for dip forming, the method including: (a) preparing a monomer mixture including a conjugated diene-based monomer, an ethylenically unsaturated nitrile monomer and an ethylenically unsaturated acid monomer; (b) introducing an additive including an inorganic solvent, an emulsifier and starch into the monomer mixture; and (c) preparing a copolymer latex by polymerizing the monomer mixture, wherein a content of the starch is 0.1 to 4.9 parts by weight with respect to 100 parts by weight of the monomer mixture.

The invention generally relates to shape memory films that are tri-functionally crosslinked and that comprise multiple, non-terminal, phenylethynyl moieties. In addition, the present invention relates methods of fabricating such films. Due to the improved properties of such SMPS, the SMP designer can program in to the SMP mechanical property enhancements that make the SMP suitable, among other things, for advanced sensors, high temperature actuators, responder matrix materials and heat responsive packaging.
