  • Simplified method of producing biodegradable aliphatic polyesters
    Patent number: 7253250
    Abstract: A method of synthesizing biodegradable aliphatic polyesters from one or more aliphatic dicarboxylic acids or diesters of the said acids and one or more linear or branched aliphatic glycols, comprising a first esterification or transesterification step and a second deglycolation under vacuum step, in which the catalyst is monobutylstannoic acid both for the esterification or transesterification step and for the deglycolation under vacuum step.
    Type: Grant

  • Use of polyester resins for the production of articles having good properties as barriers to water vapor
    Patent number: 6727342
    Abstract: Polyester resins formed by recurring units X=[O—(CH2)n—OCO—(CH2)m—CO] and/or Y=[O—(CH2)k—CO], where the half-sum of n+m is equal to or greater than 6 and k is a number equal to or greater than 6, or by copolymers comprising units and/or sequences having the formula xi[O—(CH2)ni—OCO—(CH2)mi—CO]; yj[O—(CH2)kj—CO] where: i,j=1-5; ni=2-22; mi=0-20; kj=1=21; (Formula (1)) and xi and yj vary between 0 and 1 and are molar fractions of the various units such that (Formula (2)), are used for the preparation of products in which a permeability to water vapour of less than 350 g×30 &mgr;m/m2 per day, measured at 38° C. and 90% RH and good biodegradability are required.
