    摘要: THE INVENTION INVOLVES NEW 5-ARYLOTRIAZOLYL 2-STYRYL BENZOTRIAZOLES OF THE FORMULA

    2-((R-PHENYL)-CH=CH-),5-(4,5-(-A-)BENZOTRIAZOL-2-YL)-

    BENZOTRIAZOLE

    WHICH ARE USEFUL AS OPTICAL BRIGHTENING AGENTS. IN THE FORMULA R IS HYDROGEN, ALKYL, ALKOXY, CARBALKOXY, ACYLAMINO, ALKYL SULPHONYL, CARBOXY, CN, AN AMMONIUM GROUP A HYDRAZINIUM GROUP OR HALO, AND A STANDS FOR THE RESIDUAL MEMBERS OF A MONO- OR POLYNUCLEAR AROMATIC-CARBOCYCLIC RING SYSTEM WHICH IS CONDENSED AS INDICATED WITH THE HETEROCYCLIC RING AND WHICH MAY CONTAIN FURTHER SUBSTITUTENTS, WHEREAS N DENOTES THE NUMBERS 1-3. THE VARIOUS R SUBSTITUENT GROUPS MAY THEMSELVES BE FURTHER SUBSTITUTED, THE PREFERRED SUBSTITUENTS ON THE ALKYL GROUPS BEING OH, CN, HALO, ALKOXY, CARBALKOXYL AND CARBOXYL GROUPS.

    摘要: Polyesters which contain hydroxyl and carbonamide groups are prepared by copolymerizing a lactone with a lactam in the presence of a low molecular weight initiator which contains at least two active hydrogen atoms at a temperature of from about 50* C. to about 300* C. These polyesters are particularly useful as plasticizers and stabilizers for polyvinyl chloride.
