    摘要: The present invention relates to surfactantless latex compositions. More particularly, the present invention pertains to surfactantless latex compositions comprising sulfo-polyester polymers wherein the compositions have a continuous phase comprising water, diol, polyol or a mixture thereof. Still further, the present invention provides methods of making polymer blends comprising a condensation polymer and a latex polymer whereby the latex polymer is derived from a surfactantless latex composition comprising sulfo-polyester polymers. Polymer blends made by such methods are also provided.
