  • Modified PET polymers and copolymers suitable for extrusion blow molding
    Patent number: 4554328
    Abstract: There is disclosed an improved modified polymer suitable for use in making hollow containers by conventional extrusion blow molding. It is a specific type of end-capped and branched polyethylene terephthalate polymer or copolymer. In the improvement, the end-cap comprises the reacted component of a difunctional acid or alkali metal salt of a difunctional acid having the formula: ##STR1## wherein: X has a valency of 6 and is selected from sulfur, selenium, and tellurium;M is an alkali metal or hydrogen; andY is hydrogen or an aliphatic group containing from 1 to 18 carbon atoms.The preferred difunctional acid is m-sulfobenzoic acid. The product typically contains few large gels having diameters greater than 0.1 mm.

  • Synthetic sizes
    Patent number: 4033922
    Abstract: Synthetic sizes for use on yarns in water jet looms are prepared by copolymerizing methacrylic acid with from about 3% by weight to about 15% by weight of acrylic acid or vinylethoxytetraethylene glycol as the comonomer. These sizes are useful as nylon warp sizes in water jet looms. They have the desired adhesion to nylon and water resistance plus non-adhesion to steel parts on the loom.
