  • Publication number: 20130187095
    Abstract: 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.

One of the methods for producing a modified natural rubber particle includes the steps of: forming inclusion complex of the multifunctional vinyl monomers having two or more carbon-carbon double bonds with a guest-protecting agent to protect at least one of the double bonds of the multifunctional vinyl monomers; graft-copolymerizing the resulting inclusion complex onto natural rubber particles or deproteinized natural rubber particles; and deprotecting the protected double bonds by removing the guest-protecting agent from the obtained graft-copolymer.

  • Publication number: 20120295048
    Abstract: The present invention is concerned with the process for preparing a cross-linked stabilised polymer composition using at least one graftable polymer stabiliser, and the subsequent use of that composition for forming pipes, for example PEX pipes. The graftable stabiliser becomes anchored to the polymer such that stabiliser activity is retained in the cross-linked product. Cross-linking can be achieved by conventional processes such as PEXa, PEXb and PEXc. Embodiments demonstrate excellent levels of antioxidant retention (as measured by oxidative induction retention after exhaustive solvent extraction) and the cross-linked product are suitable for portable water applications, including hot water applications.
