Abstract:
The invention concerns a novel chain-terminated polymeric composition, comprising hydroxyl-terminated polyesters and a method for preparing the composition and the use of the chain-terminated polymeric composition as a plasticizer. They play a predominant role in the field of metal vacuum closures (Twist-Off and Press-On-Twist-Off closures). Selection criteria regarding the suitability of plasticizers in food contact applications are properties such as low plasticizer volatility, low plastisol viscosity, PVC compatibility, softness and resilience of the gasket as well as non-toxicity and high plasticizer migration resistance. The invention concerns the chemical equation of FIG.  1  for obtaining the suggested chain-terminated polymeric composition, wherein x, y, and z are the stoichiometric ratios of dibasic carboxylic acid (DCA), glycerol or polyglycerol (GPO), and monobasic carboxylic acid (MCA), k is the number of methylene groups in the dibasic carboxylic acid, (k+2) is the number of carbon atoms therein, m is the degree of polymerization of polyglycerol used, (m+2) describes the hydroxyl functionality thereof, l is the number of methylene groups in the monobasic carboxylic acid, (l+2) is the number of carbon atoms in the monobasic carboxylic acid, and n is the degree of polymerization of the polyester formed by glycerol or polyglycerol and the dibasic carboxylic acid.

Claim (Index 40):
The chain-terminated polymeric composition of  claim 27 , wherein the monobasic carboxylic acids having an even number of carbon atoms.
