    摘要： A novel method of preparing an aqueous dispersion of non-uniform polyurethane particles which comprises (a) preparing at least two isocyanate-terminated polyurethane prepolymers having different hydrophilicities; (b) preparing a uniform mixture of said prepolymers, and (c) dispersing the mixed prepolymers in an aqueous medium. The resulting dispersion of the prepolymers may optionally be chain extended. This method enables the preparation of core-shell particles as well as particles of other morphologies, including “raspberry”, interpenetrating network, “salt-and-pepper”, “ice-cream cone” and particles of gradient composition. Similarly, an aqueous dispersion of two different polyurethane polymers may be obtained by first preparing at least two different isocyanate-terminated polyurethane prepolymers, preparing a uniform mixture of such prepolymers and thereafter dispersing the mixture in an aqueous medium.

    摘要： An emulsion or suspension polymer comprising a vinyl chloride polymeric core and an acrylic ester-acrylonitrile polymeric shell is disclosed. The emulsion polymer is preferably prepared using a two-stage process. In the first stage, a vinyl chloride monomer is polymerized or copolymerized to form a first phase of a polymeric hard core having a relatively high chlorine content. In a second stage, the soft acrylic ester—acrylonitrile copolymer is made in situ in a reaction mixture comprising the first phase. The product provides both flame retardancy and low MFFT, and is useful in a variety of coating and binding applications.

    摘要： An emulsion polymer comprising as one of its components a graft copolymer of a residual aromatic monomer-free support resin polymer and a vinyl chloride (co)polymer is disclosed. The emulsion polymer is prepared using a two-stage process. In the first stage, a chasing monomer is reacted in the presence of a support resin polymer having at least one aromatic monomer to form an polymer which is free of residual monomer and has monomeric units derived from the aromatic monomer(s). In a second stage, the vinyl chloride emulsion (co)polymer is made in situ in a reaction mixture comprising the polymer which is free of residual monomer. An extensive grafting at the second stage yields a novel water dispersible graft copolymer containing both styrene and vinyl chloride.

    摘要： Fibers in non-woven fibrous goods are bonded together by a crosslinked carboxylated acrylate polymer which forms a network of coalesced latex particles bonding contiguous fibers. This network exists as a non-continuous, porous film supported upon the fibers of the non-woven goods. The particles are of polymer derived from a crosslinked carboxylate latex containing from 1-20 phr of itaconic acid (IA) and at least 70 phr of one or more copolymerizable monomers one of which is an acrylate having the structure ##STR1## wherein R.sub.1 is hydrogen or methyl;R.sub.2 represents C.sub.1 -C.sub.20 alkyl, C.sub.2 -C.sub.7 alkoxyalkyl, C.sub.2 -C.sub.7 alkylthioalkyl, or C.sub.2 -C.sub.7 cyanoalkyl; andat least 40 phr of said acrylate in said film is present as an alkyl acrylate in which alkyl is C.sub.4 -C.sub.8.The network can only be derived from a latex which has been formed by an emulsion polymerization process in which at least one-half of the IA is initially charged into a reactor, and the remaining ingredients of the recipe then added gradually. The unique order of addition produces a concentration of carboxyl (COOH) groups on the surface of the latex particles which is at least twice that of COOH groups on particles of a latex formed by conventionally proportioning the monomer ingredients after initiation. This distribution of COOH groups persists in the coalesced latex particles, and results in a polymer having higher tensile strength and toughness than might be expected in a polymer with such low T.sub.g in the acrylate family.

    摘要翻译： 非织造纤维制品中的纤维通过交联的羧化丙烯酸酯聚合物结合在一起，其形成结合邻接纤维的聚结胶乳颗粒的网络。 该网络作为非连续的多孔膜存在于无纺织物的纤维上。 颗粒是衍生自含有1-20phr衣康酸（IA）和至少70phr一种或多种可共聚单体的交联羧酸酯胶乳的聚合物，其中一种是具有结构式（I）的丙烯酸酯，其中 R1是氢或甲基; R2表示C1-C20烷基，C2-C7烷氧基烷基，C2-C7烷硫基烷基或C2-C7氰基烷基; 并且所述膜中至少40phr的所述丙烯酸酯以丙烯酸烷基酯的形式存在，其中烷基是C 4 -C 8。 网络只能从乳液聚合过程形成的胶乳得到，其中IA的至少一半最初装入反应器中，然后逐渐加入配方的其余成分。 独特的添加顺序在胶乳颗粒表面产生羧基（COOH）基团的浓度，其为通过在引发后常规配比单体成分而形成的胶乳颗粒上的COOH基团的至少两倍。 COOH基团的这种分布仍然存在于聚结的胶乳颗粒中，并且导致聚合物具有比在丙烯酸酯族中具有如此低的Tg的聚合物中预期的更高的拉伸强度和韧性。
