Abstract:
Resin compositions comprising alpha-methylstyrene/tertiarybutylstyrene/olefin terpolymers, ethylene/vinyl acetate copolymer, and paraffin wax are useful as hot melt adhesives.
Abstract:
New polymeric resin compositions are prepared by copolymerizing alpha-methylstyrene, tertiary butylstyrene and an olefin e.g., isoprene and 2-methyl-2-butene. Such resins are useful as hot melt adhesives.
Abstract:
POLYBUTYLENE Terephthalate Reaction of terephthalic acid and butane diol using a tetravalent tin catalyst having one organo-to-tin linkage. This invention relates to the production of polybutylene terephthalate by reacting terephthalic acid and 1,4butylene glycol in the presence of tetravalent tin catalyst having one organo-to-tin linkage.
