摘要： A method produces polar-modified rubber and olefin thermoplastic waste by grafting during a grinding process, for treatment, usable as compatibility agents in various plastic blends and composites, without the disadvantages of known functionalized recycled plastics, particularly the mechanical characteristics that are insufficient for their use. The waste is simultaneously ground and graft-modified in a temperature range between 40° C. and 140° C., in one method step. Scrap parts of vulcanized elastomer or olefin thermoplastic are comminuted to a particle size diameter of approximately 4 and 8 mm. The waste should be sorted by type, if possible. The shredded material is mixed with at least one organic peroxide and an α,β-ethylene compound possessing at least one unsaturated polar group. The mixture is simultaneously ground and grafted at a specified dwell time and temperature range to a particle size diameter

摘要： The present invention provides heterocyclic vinylic compounds that can be used to form biocidal polymers. The polymers thus generated can be used alone or can be grafted onto textiles, fabrics and polymers. The polymers are readily converted to N-halamine structures on exposure to a halogen source such as commercially available chlorine bleach. The N-halamine derivatives exhibit potent antibacterial properties against microorganisms and these properties are durable and regenerable.

摘要： A pressure sensitive adhesive/cohesive exhibits excellent cohesive body properties, and other desirable features, even when exposed to heat and polysiloxane based lubricants, such as in a laser printer. The formulation comprises 100 parts by weight natural rubber (e.g. electrosterically stabilized natural rubber graft and block terpolymer), and expressed as percentages by weight of the rubber the following components: about 5-35% (e.g. about 28%) acrylate monomer or monomers (such as methyl methacrylate, cyclohexyl methacrylate, benzyl methacrylate, and/or isobornyl methacrylate); about 0.5-8% acrylic acid and/or about 1-10% 4-acetoxystyrene; about 0-20% ethyl hexyl acrylate; about 1-50% (e.g. about 10-30%) finely divided hard particulate material (such as silica gel); 0-50% (preferably about 10-30%) starch; and 0-40% (preferably at least about 5%) carboxylated styrene-butadiene latex, or carboxylated polychloroprene latex, or a styrene-acrylate-acrylonitrile latex, or vinyl-pyridine styrene-butadiene latex, or pre-crosslinked natural rubber latex, or a tackifier, or combinations thereof. The cohesive is coated onto paper and seals to like cohesive upon the application of a force of at least 100 lbs per lineal inch.
