Принадлежит: DESIGNER MOLECULES, INC.

The invention is based on the discovery that adhesive compositions containing certain low-viscosity, mono-ethylenically unsaturated monomers have surprisingly good cure parameters, resulting in very little weight loss upon cure. Many of these monofunctional monomers used alone or in combination with other monofunctional monomers described herein have high glass transition temperatures when cured. Moreover, since these monomers are monofunctional the crosslink density of the adhesive composition does not increase (relative to multi-functional monomers), which in turns results in lower stress, lower modulus adhesive compositions. As such, these monomers are useful in a variety of thermoset adhesive compositions, such as for example, die attach adhesive compositions. 2.

The use of hot melt adhesives is widely used in packaging industry to seal containers, e.g. cardboard cases, trays and cartons. Many types of packaging applications require the use of an adhesive that is both heat resistant and cold tolerant. However, conventional hot melt adhesives exhibit strong bond strength at either the high or the low end temperatures, but not both. Polypropylene based systems have been utilized to improve heat resistance, but polypropylenes provide inadequate cold resistance because they become brittle at around 0° C. During transportation and storage, and depending on the season and location, the sealed containers are exposed to temperatures of from about −20° F. to about 140° F.
