  • Publication number: 20230104319
    Abstract: The present disclosure is directed to a formulations of cements and methods for bonding dissimilar materials. The formulations and methods can bond a Non-polyvinyl chloride (PVC) containing first polyolefin that is amorphous or has low crystallinity to a second material that is a rigid material or a hard PVC. The methods and formulations can work by co-dissolution at an interface, or activation of a one of the materials prior to bonding.

  • Patent number: 11198801
    Abstract: Amphiphilic graft copolymers comprise a polypropylene backbone and hybrid micromolecule side-chains based on organo-functional silanes (PP-g-XSiOA) in the presence of a co-agent, for example, difunctional metallic diacrylate monomers, where “X” is an organic group or an organo-functional group, and “A” is a metal, an inorganic oxide, an inorganic hydroxide, or any other inorganic material. X may be derived from a compound selected from the group consisting of epoxy, amino, acrylate, methacryloxy, and vinyl; and A is selected from the group consisting of: silicon, (Si), aluminum (Al), iron (Fe), titanium (Ti), silver (Ag), zinc (Zn), nickel (Ni), calcium (Ca), copper (Cu), tin (Sn); oxides thereof; hydroxides thereof; and mixtures of the foregoing. These copolymers are suitable for forming medical devices and/or as additives to base polymeric formulations for medical devices for improving laser marking, antimicrobial resistance, adhesive free bond strength, paintability and dyeability.
