1. An encapsulate comprising a core, a wall having an outer surface and a coating, said wall encapsulating said core, said coating coating the outer surface of said wall, said coating comprising one or more efficiency polymers having the following formula: wherein:
a) wherein a and b are integers or averages (real numbers) from about 50-100,000;b) each R1 is independently selected from H, CH3, (C═O)H, alkylene, alkylene with unsaturated C—C bonds, CH2—CROH, (C═O)—NH—R, (C═O)—(CH2)n—OH, (C═O)—R, (CH2)n-E, —(CH2—CH(C═O))n—XR, —(CH2)n—COOH, —(CH2)n—NH2, —CH2)n—(C═O)NH2, the index n is a integer from about 0 to about 24, E is an electrophilic group; R is a saturated or unsaturated alkane, dialkylsiloxy, dialkyloxy, aryl, alkylated aryl, that may further contain a moiety selected from the group consisting of cyano, OH, COOH, NH2, NHR, sulfonate, sulphate, —NH2, quaternized amines, thiols, aldehyde, alkoxy, pyrrolidone, pyridine, imidazol, imidazolinium halide, guanidine, phosphate, monosaccharide, oligo or polysaccharide;c) R2 or R3 can be absent or present:
(i) when R3 is present each R2 is independently selected from the group consisting of —NH2, —COO—, —(C═O)—, —O—, —S—, —NH—(C═O)—, —NR1—, dialkylsiloxy, dialkyloxy, phenylene, naphthalene, alkyleneoxy; and each R3 is independently selected the same group as R1;(ii) when R3 is absent each R2 is independently selected from the group consisting of —NH2, —COO—, —(C═O)—, —O—, —S—, —NH—(C═O)—, —NR1—, dialkylsiloxy, dialkyloxy, phenylene, naphthalene, alkyleneoxy; and each R3 is independently selected the same group as R1; and(iii) when R2 is absent, each R3 is independently selected the same group as R1;d) said one or more efficiency polymers having an average molecular mass from about 1,000 Da to about 50,000,000 Da; a hydrolysis degree, when said efficiency polymer is a polyvinyl formamide, of from about 5% to about 95%; and/or a charge density from about 1 meq/g efficiency polymer to about 23 meq/g efficiency polymer. |
