Abstract
This invention relates to a composition comprising (a) at least one polymer selected from the group consisting of poly(chlorotrifluoroethylene) and copolymers of chlorotrifluoroethylene and one or more ethylenic comonomers; wherein said copolymers comprise at least about 50% by weight of chlorotrifluoroethylene and (b) effective amount of one or more nucleating agents selected from the group of compounds consisting of silver octonate, calcium carbonate, potassium benzoate, talc and lays bentonite, montmorillonite, hectorite and derivatives thereof.
Claims24
A composition comprising (a) at least one polymer selected from the group consisting of poly(chlorotrifluoroethylene) and copolymers of chlorotrifluoroethylene and one or more ethylenic comonomers;
- wherein said copolymers comprise at least about 50% by weight of chlorotrifluoroethylene and (b) effective amount of one or more nucleating agents selected from the group of compounds consisting of silver octonate, calcium carbonate, potassium benzoate, talc and lays bentonite, montmorillonite, hectorite and derivatives thereof.
A process for enhancing the rate of crystallization of a polymer selected from the group consisting of poly(chlorotrifluoroethylene) and copolymers of chlorotrifluoroethylene and one or more ethylenic comonomers;
- wherein said copolymers comprise at least about 50% by weight of chlorotrifluoroethylene from the melt, which comprises adding to said poly(chlorotrifluoroethylene) a crystallization enhancing effective amount of one or more nucleating agents selected from the group of compounds consisting of silver octonate, calcium carbonate, potassium benzoate, talc clays selected from bentonite, montmorillonite, hectorite and derivatives thereof.
A composition comprising (a) at least one polymer selected from the group consisting of poly(chlorotrifluoroethylene) and copolymers of chlorotrifluoroethylene and one or more ethylenic comonomers;
- wherein said copolymers comprise at least about 50% by weight of chlorotrifluoroethylene and (b) one or more compounds selected from the group of compounds consisting of silver octonate, calcium carbonate, potassium benzoate, talc, bentonite, montmorillonite, hectorite and derivatives thereof;
- wherein sum of weight percent of the compounds of (b) is about 0.001 to about 5 percent based on the total weight percent of the polymer or copolymer.
