An improved polymeric compositions containing 1,3-diphenoxy-2-propanol as a heat stabilization agent and antioxidant is provided. This invention relates to polymeric compositions containing 1,3-diphenoxy-2-propanol as a heat stabilization agent, and antioxidant, and, optionally, as flow control agent; more particularly, this stabilizer is especially suited to protect polymeric coatings- and adhesive which are heated and flow, such as hot melt coating- and adhesive compositions.
A fusible interlining has a textile substrate employed with a single adhesive layer and is intended to be bonded to drapery. The adhesive layer includes a first phase in the form of thermoplastic powder of dense granules whose primary function is to ensure the adhesion of the fusible interlining to the drapery at the time of bonding. A second phase of the adhesive layer is a crosslinkable system including a crosslinkable resin and a hardener in the form of a homogeneous matrix whose main function is to coat the granules of the thermoplastic powder of the bonding system.
Phase change compositions that are solid at ambient temperature and liquid at an elevated temperature above ambient temperature are disclosed for advantageous use in selective deposition modeling methods for building three-dimensional objects. A phase change composition according to the disclosed invention is a semi-crystalline component mixture having a freezing point of at least about 68.degree. C., a melting point of at least about 88.degree. C. and a viscosity of about 13 centipoise at 135.degree. C. The composition includes a plurality of waxes having a broad melting point range and molecular weight range. Three-dimensional objects having minimal curl, delamination and stress cracks can be produced at a faster rate than heretofore known by using selective deposition modeling techniques employing the disclosed compositions.
