摘要:
An adhesive formulation such as a hot melt adhesive or a pressure sensitive adhesive is provided comprising 5 to 98% (by weight) biodegradable substantially non-crystalline mcl-PHA. The mcl-PHA may be cured with a peroxide curing agent. The adhesive formulation may include an additional biodegradable polymer, or a non-biodegradable thermoplastic elastomer. Hot melt adhesives comprising significant amounts of biodegradable mcl-PHA, waxes, and tackifiers are also provided.
摘要:
An oligoester composition which is a reaction product of a reactant mixture comprising one or more rosins; at least 15% by weight of one or more monocarboxylic acids; and one or more polyhydric alcohols. A method for preparing an oligoester composition comprising (a) esterifying a mixture comprising one or more rosins, one or more monocarboxylic acids, and optionally one or more polycarboxylic acids with one or more polyhydric alcohols to form the oligoester composition. An oligoester composition which is an esterification reaction product of one or more rosins, one or more monocarboxylic acids, one or more polyhydric alcohols, and optionally one or more polycarboxylic acids, wherein the composition has a weight average molecular weight of from 500 g/mol to 8,000 g/mol and a Tg of between -80°C and 100°C.
摘要:
The present description relates to an adhesive asphalt or tack coat composition, and method of use. In particular, the tack coat compositions comprise an asphalt binder material, a resin, an emulsifier, and a polymer, wherein the tack coat is non-adhesive at ambient temperatures and adhesive when heat is applied.
