    Abstract: Acrylic copolymers incorporating high Tg, hydrophobic (meth)acrylate monomers that have high thermal stability, especially under hot, humid conditions are provided. The acrylic copolymer includes, as polymerized monomers, a combination of monomer a) and monomer b). Monomer a) includes at least one of tert-butyl cyclohexyl (meth)acrylate, 3,3,5-trimethyl cyclohexyl (meth)acrylate, or a mixture thereof. This monomer or monomer blend a) is present in the acrylic copolymer at from 0.2 to 20 weight percent and includes at least 80 weight % trans isomer. Monomer b) is (meth)acrylate and is present in the acrylic copolymer at from 80 to 99.8 weight percent of the acrylic copolymer. The acrylic copolymer has a Tg of from 116° C. to 145° C. and a weight average molecular weight (Mw) of at least 65,000 g/mole.

    Abstract: A polyolefin composition made from or containing:
    T1) 70-95 wt %, a polyolefin component containing:
    a1) from 30 wt % to 70 wt % of a propylene based polymer; and
    a2) from 30 wt % to 70 wt % of an ethylene based polymer;
    the sum of a1) and a2), being referred to the total weight of a1) and a2), being 100; and
    T2) 5-30 wt % of a propylene ethylene copolymer containing from 2.0 wt % to 10.0 wt %; of ethylene derived units and having a melt flow rate (230° C./2.16 kg) ranging from 0.5 to 20.0 g/10 min, and having a fraction soluble in xylene at 25° C. lower than 20 wt %.

    the sum of the amount of T1) and T2), being referred to the total weight of T1) and T2), being 100.

    Abstract: The aim of the present invention is to provide a copolymerized polyester resin for solving the problem of die staining and foreign matter adhesion to the film etc. in the continuous production of the film etc.; and the problem of recycling property of the copolymerized polyester. This copolymerized polyester resin contains dicarboxylic acid and did as constituting components, wherein the copolymerized polyester resin contains terephthalic acid as a main component of a dicarboxylic acid component, and contains ethylene glycol as a main component of a diol component, wherein a content of diethylene glycol is from 7 to 30% by mole and a content of triethylene glycol is from 0.05 to 2% by mole when a total amount of the whole diol component is taken as 100% by mole, wherein a content of a cyclic dimer consisting of terephthalic acid and diethylene glycol is 7000 ppm or less, and wherein a content of a cyclic dimer consisting of terephthalic acid, diethylene glycol and triethylene glycol is 200 ppm or less.
